Circa 1935 POP Up Books

A friend of mine lost his father recently.  While going through his father's belongings he found several 1935 pop up books in awesome condition.  He and his sibs had not had access to them, and had no emotional attachment to them --- so I am putting the books on ebay for him.

 They are in such great condition,

and the pop ups are so 3-dimensional and well done.

 These three characters became more popular

and endured through time.

But there were several other pop up books with

heroes whose names are less well known.

Heading to ebay the first week of March.
