This one is dated September 1942 from a magazine called Playthings.This is also a Wards listing and note the Mildred Wirt books on the right side, advertising Brownie Scout and Dan Carter Cub Scout books.
Finally, these are photos of a Grosset & Dunlap catalog from the early 1970s. I had this in my collection for a good 30 years and sold it a few years ago for about $50. Considering this was a free catalog, that is a pretty good investment for saving it all those years. The interesting thing about it is some of the books in the catalog are very hard to find books because they were books issued at the end of the particular series, so there are few copies out there to find and thus they have a higher value today. This is particularly true of the Rick Brant books for sale in this catalog. I wish the photos were better, but these were take by a camera and not a scanner. Still it is an interesting item. And in case you were wondering, I am the one who marked up the list to indicate what books I had at that time. I guess I didn't think much of it being a collectable then or I wouldn't have marked on it, but I was a kid then and we all know how kids like to mark in their books.
