Children's Books discussion

Hi, I am throwing a message in a bottle to see if I can ring any bells. My friend is ga-ga for a Mr. Peabody and Sherman book that her mother used to get her from the library when she was a child. The mother has now died, the book holds dear memories, and I have very little to go on.

This book would have been published prior to 1999 — my friend was born 1987 and this would have been age-appropriate for a 3-8 year-old, and from the way she speaks of it I infer that she was about 5. She describes the book as a relatively large-format book with an audiocassette accompanying. The characters go on an adventure that somehow involves rainbows. She describes the cover as predominately yellow. She claims it was not a Golden Book, but I think she may be mistaken.

I am striking out solidly. Any recollections of such a book, or of authors of such books, or of series of such books from that time period would be vastly appreciated. Thanks in advance.

Fearless Firemoose! features these characters, reminding us that they're related to Rocky & Bullwinkle. Also the creator given most of the credit is Jay Ward (who apparently needs an author disambiguation).

There's also this: https://www.ebay.com/itm/Mr-Peabody-S...
I don't see it here on GR. It may be an activity book.

To clarify, I don't think I've found the answer... just some more clues to help someone who is a better researcher than I. Oh, and do know that the original TV show is much older than your friend... I saw a date of 1959.

This doesn't ring a bell for me but I wish you luck in your search, Davis. I know how special these treasured childhood books can be!

There is a group on GoodReads to help people track down books, so you might post there if you haven't done so yet:
What's the Name of That Book???

Moved to the correct folder.

The OP should check on ABE Books and put Mr. Peabody and Sherman in the keyword section doing an advanced search. There are quite a number of Mr. Peabody and Sherman books listed, most with bright cover images.
