This block set belonged to my father who played with them as a child. He was born in 1902 so I suspect that this set was purchased before 1905. This is a set that came in a wooden box with a sliding lid. On the under side of the lid is a color picture showing how the blocks fit back into the box. When I as a kid the picture on the wooden box was pretty but my brother covered it with tape & later removed it. Therefore the orignal information about these blocks has been lost.
The first photo shows both the box and it's contents as well as the under side of the sliding lid. The second photo shows the closed box.
From the above photo you can see that there are a lot of pieces to this set in all sorts of shpaes and sizes. A few are broken and a few may be missing. There are between 50 and 70 pieces to this set.
