This second edition has a number of clues which make it easily identifiable from the first. Most obviously, it has the words "2nd Printing" on the front cover. It's also 3˘ cheaper. But it also has an entirely different back cover. Whereas the first edition has a one-page story on the back, this one has an ad for Daisy air rifles. Note, too, that this edition came out considerably later than the original; in fact, Four Color was cancelled by the time it hit the shelves.
