This one also belongs to the Simak estate -- of course, that's because it contains a Simak story ("The Voice in the Void").
WONDER STORIES QUARTERLY was, like WONDER STORIES, a Hugo Gernsback production. The issue shown is vol. 3, no. 3, from Spring, 1932.
The cover illustrates the story "The Vanguard to Neptune," by J.M. Walsh. It makes up nearly half the magazine (which is half an inch thick, more than twice the size of the regular WONDER STORIES issues that I've seen).
(I should add that both varieties of WS were larger than more regular sf magazines -- like the "bedsheet" format that popped up now an again in sf magazine publishing over the years. The issue shown measured 8.5 x 11-3/8 x .5 inches.
This issue also featured stories by Manly Wade Wellman and Jack Williamson (just mentioning names we might recognize...).
There's no indication who did that cover, but, as usual with WS, the Art Director was Frank R. Paul -- there were a lot of interior illos, and he did (and signed) many of them.
As for the cover story, "Vanguard" -- it was not very good...one of the sort that seemed to exist for the purpose of letting the author show off the variety of alien races and technologies that he could dream up...they were introduced one after another, with the dangers they presented to the crew of Earthmen each rapidly disposed of...
I started wishing for the end, after a while...
