Illustrations by William F. Heitman or attributable to William F. Heitman, from Weird Tales magazine. From top to bottom: "Hypnos" by H.P. Lovecraft (May/June/July 1924); "Imprisoned with the Pharaohs" by Harry Houdini (May/June/July 1924); "The Rats in the Walls" (Mar. 1924) by H.P. Lovecraft; "The Hound" by H.P. Lovecraft (Feb. 1924); "The White Ape" by H.P. Lovecraft (Apr. 1924). The only one of these five illustrations with a signature is the last, but before the November 1924 issue--the first with Farnsworth Wright as editor--only William Heitman received credit as an interior artist. These illustrations look to be the work of one artist. I think it's safe to assume they're all by Heitman. I can comment on their quality as well, if only to say that, judging from these illustrations, Robert Weinberg may have been a little hard on Heitman. Each has its merits. The illustration for "The White Ape" (also called "Arthur Jermyn") I think is most effective and my favorite among them.
These images are courtesy of Alan Husby. I have altered them somewhat to improve their appearance (I hope) and to remove the text.
