rejon linked to "650 Soviet Book Covers" (public domain) and I could only find low resolution downloads (without cheating) but I thought I'd provide one sourced from there anyway, in the spirit of cooperation. This one isn't a literal direct rip from the original cover. I removed a simple biplane and cropped it a bit to focus on the old flag and the desolate landscape.
