Exact last issue number is uncertain.
"Peter Wheat News" was a monthly publication, consisting of a sheet of paper folded into a four page flyer. The first two pages consisted of a front page and one page of recipes, news from and advertisements for the Peter Wheat bakery chain. The last two pages were intended to be cut out and could be folded into a four page 5 1/2" x 7 3/8" "Adventures of Peter Wheat" comic book.
Issue number can be found solely on the original front cover, meaning that copies handled as originally intended are hard to identify, unless a copy with front cover can be found.
