1907 Childs Play Toy blocks

Old set of toy blocks I got at a garage sale in Lansing back in 72'. Don't remember what I paid but it was a very old lady who sold me 75+ year old paperweights and newer for $5 each! The first 2 pic's show both sides of the same blocks. I'm sure it's not the whole set but I thought they were cool and unusual. Figured I'd make my money back plus some in the years ahead. Just wish I had bought-en more stuff in the seventies now! lol All the detail is raised.... carved or pressed. These are from solid boards... you can see the wood grain in them. They are made to build a house or a building. I have searched and searched and cannot find anything similar. Little help please if you know anything about them. I see block sets for sale for $400 and mine seem to blow them all away for rarity and uniqueness. Tell me what you think.

The dimensions of the majority of small squares on the left side are
1 3/4" square by 3/4" wide...
