Otis Adelbert Kline was one of the foremost writers practicing the Planetary Romance genre in the
1930s.  Working in the tradition established by Burroughs' Martian novels, Kline wrote five novels of
interplanetary adventure set on Mars and Venus.  Many readers and critics consider Kline's Venus
series to be much better than Burroughs' own Venus series.  Following World War II, Kline's work
was all but forgotten.  However, many a reader rediscovered their sense of wonder in Kline's stories
published by specialty house Avalon Books in the late 1950s and 60s.  Since then, Kline has not been
out of print for the past sixty-plus years.  And no end is in sight, because as long as readers love
romance [every meaning of that word is implied] and high-adventure mixed with an exotic locale,
Kline and the
planetary romances will flourish.

The Venus Series was originally published complete in the editions listed below:

The Planet of Peril  (1929) McClurg, Grosset & Dunlap
The Prince of Peril (1930) McClurg
The Port of Peril (1949) Grandon.

In the 1950s the first two books in the series were reprinted in an abridged form (approximately 25 to
30% less text) by Avalon Books.   Avalon was a science fiction logo for a publishing company that
catered especially to libraries.  This is where I first encountered Kline.  ACE Books reprinted the
books in the 1960s using the abridged Avalon text.  If you want to read unabridged Kline, the original
hardback publications listed above, the Jerry Schneider publications at www.pulpvillepress.com,
and the Black Dog Books reprints are the only places you can find him complete and unabridged.

The variants seen below are built around the public-domain Roy G. Krenkel illustrations created for
the ACE Books reprints of Kline in the early 1960s.  I doubt if I will ever sell all three variants as a set.
It's just too difficult to find all three of these books in affordable editions today.  However, making
variants for my favorite authors is just fun and challenging, and I wanted a set for my own collection.  
Whether or not you ever buy a variant dust jacket, I hope you appreciate the skill and whimsy that go
into creating them.
