The perk magazines in "Fallout 4" feature some covers of interest to Lovecraft fans. I suspect that the "Astoundingly Awesome" pulps foreshadow the DLC content that will be released next year. Based on these two I think it's safe to say at least one will feature an underwater adventure touching on the Mythos. A few others hint at a potential trip to the moon.
You can find a full gallery of all the magazines over here. The resolution is a bit low for prop versions, but weathering can cover up a multitude of sins.
If you're really into potential Fallout/Mythos crossovers, this thread over at Reddit has me geeking out on the lore of the "Cabot House" quest in FO4. Beware, it's filled with some very big spoilers.
