Golden age comics digitally republished for your viewing pleasure on the Amazon Kindle. America's Greatest Comics is an 8 issue series featuring the adventures of Captain Marvel, Bulletman, Spy Smasher, Mister Scarlet, Minute Man, and more!
I stumbled across this as a free download. It is a reproduction of issue #4 of America's Greatest Comics. It includes several stories with different characters ranging from Shazam to Spysmasher. It came out during World War II.
This comic has one huge problem. The way it is reproduced for the Kindle. It looks like someone simply photocopied the pages. It is grainy, and even worse, in black and white. It is hard to read in spots because of this. The pages are fairly small. You can enlarge the entire page but have to shrink it again to turn to the next page.
For some unknown reason, they include a table of contents at the end. But it simply lists every page number (page one, page two, page three, etc for all long hundred plus pages) with no additional information.
So a great piece of comic book history but presented in a horrible fashion.
