Three of a Kind - Harry E. Rieseberg

 Harry E. Rieseberg wrote a number of books with "treasure" in the title, all mixing fact with a healthy dose of fiction! Here are some examples:

1942

I've featured this 1954 paperback cover before but thought I might as well include it again here as a bonus:

1957

I'm assuming the title of this one reflects his minimalist phase!

Artwork by Albert Orbaan whose other work includes The Real Book About Mountain Climbing, No Room for a Dog, Battles and Bloodshed and the Mike Mars Astronaut series.

1962

Cover by Donald M. Yena (b.1933), an artist primarily known for his western paintings.

Two of a Kind - Red Sea Diver's Guide

My first visit to the Red Sea was in 1998 and I returned in 2000, with many subsequent visits. I remember having a copy of the second volume here on some of those early trips. I've dived the wreck on the cover, the Giannis D, many times but I don't think I've ever seen a diver quite as colourful as the one portrayed! I particularly like the way the artist has depicted the reflections on the surface. The first volume is a recent discovery for me. The diver's pose is somewhat unusual but it's certainly a striking design.
