Quality Control - How these facsimiles are made
From an original:
I don't make perfect reproduction dust jackets.  I'm not even sure that can be done, although Phil Normand at recoverings.com comes close.  I generally start with an original dust
jacket that is almost always damaged in some way - discolored, faded, ripped, chipped, etc.  I make as good a scan as possible, always looking for color and intensity problems.  
After that it's up to my skill with photoshop, photoimpression, Windows Paint, and other image manipulation programs to repair the original scan to as close to an original state as
possible.  Sometimes portions are missing from the DJ, and I simply have to make an educated guess as to what should appear in the missing area.   See an example of this
process immediately below.
Original scans, followed by the final versions of the corrected facsimile dust jackets.

As you can see, sometimes I have a lot of material to work with.  Sometimes the original is very beat up indeed, as in
The Pirates of Venus above.
No original available:
Many companies often published  reprints in relatively uniform editions.  Therefore, sometimes even if I have no original from which to work, I can construct a facsimile that very
closely resembles an original by  starting with a front cover scan and then using bits and pieces of other dust jackets in the uniform reprint series to complete the facsimile.  This
technique is most useful for the Grosset & Dunlap and the ERB Inc. 1948 editions which used uniform back covers and back flaps for individual print runs.  
 (NOTE: This method
doesn't work for first edition jackets, because each is unique.)  
See an example of this process immediately below.
Image 1 - A friend emailed this partial
DJ  to me from his own collection.  He
was missing the rest of the dust jacket
Image 2 - From Zeuschner I learned that the
first G&D reprint had twelve titles listed on
the back cover of the DJ.  This image came
from a G&D Tarzan book.
Image 3 - From a poor eBay
image, I retyped and imaged
the front flap from scratch.  I
couldn't get an exact match on
the font, but I came close.
Image 4 - The back flap was taken from a
file of examples of flaps that I keep on
hand for just this sort of problem.  This
particular back flap came from a G&D
edition of
The Eternal Lover.
Image 5 - The finished facsimile. . . I was never going to get a "white" background" from the faded and aged original I started from.  
So I decided to reproduce as accurately as possible all the information in the dj as published, but keep the aged, antique look of the
cover-and-spine scan I was originally sent.  To do this I deliberately "aged" the entire dj by inserting digital scratches and scuffs. I
then began to adjust the color balances throughout the image.   I wanted an appearance of cohesion, i. e. a color fade/hue/tone
match from one part of the dj to another.  When I finally had achieved what I believed to be cohesion of all elements, I stopped,  then
ran it off to ensure the fit on my own book.  After three false starts, each requiring slight manipulations of the dimensions of the DJ,
the fit was finally right.  
Images 8 and 9 - The facsimile mounted on my copy.
Image 6 - I thought I was finished, but was never really happy with the
facsimile.  As soon as I located another, brighter image, I enhanced it,
and corrected some areas, but not many.
Image 7 - After some corrections in the sky area, then balancing and enhancing the image.  I put all the parts together
again and the end result is to the above jacket as it currently exists.

Jackets that closely resemble the original --- i.e. faded, discolored, but still attractive, like this one ---  I call "antiqued."
The only things missing in this particular jacket are the chips at the edges normally found in an original of this title. To
compare it to a version that has been cleaned up to look newer go
FINAL ASSEMBLY - I won't make or sell a facsimile that I have not personally fitted on an edition in my own collection.  Too
many things can go wrong. It's just too hard to be sure that it fits otherwise. Once I know that the facsimile fits my own
copy of the book, then I am ready to sell it.

As an order is made, either on eBay or through this web site, I cut the blank paper from a roll of professional grade bond
paper.  Next, I print the desired facsimile at the highest possible grade that I can on my home computer system.  Then I
allow it to dry completely.   Then I fit each facsimile on my copy of the book to ensure that it is fitted correctly.  Next, I fit a
protective mylar library cover over the printed facsimile.  Last, I pack the prefit facsimile DJ between two full size pieces
of cardboard and seal the entire package with plastic packing tape to ensure that it is moisture proof.

My guarantee to you is that you will receive a quality facsimile produced at the highest level of craft possible using the
equipment and techniques that I employ.  In the seven years that I have been doing this hobby, I've never had a complaint
from any customer.   However, anything is possible; so, if you run into any difficulty with your DJ or if you are dissatisfied
in any way, call or email me immediately.  Your money will be cheerfully refunded upon your request.  See the "About
