Infinity covers are a great deal of fun. And this 1946 Captain Marvel Jr. cover is especially so since it also showcases a bunch of other "real" comic book covers from the Fawcett publishing lineup. I guess in this fictional universe all Freddy is allowed to sell are Fawcett comics. Such a scheme reminds me somewhat of what Marvel tried to do to direct sales outlets in the 90's, much to the chagrin of the whole industry.
Here are the covers featured on Freddy's stand, as best as I can make out.
