The Really Cool Adventures Of Captain Underpants

The Really Cool Adventures Of Captain Underpants (not to be confused with the comic book of the same name) is an extremely rare book created by Dav Pilkey and self-published in 1989. It is a prototype of The Adventures of Captain Underpants. 50% of its profits were donated to Goodwill and the United Way. Only one copy still remains in existence and it is unknown where it is. There is a chance this cover could be false.
