Does anyone have any idea of how these childrens blocks were carved? The one in the photo is from the late 1800's or early 1900's so I know it wasn't laser or CNC router technology. The relief of the carvings is about 1/16". My wife has a large collection of these antique blocks. The carving seems to vary from 1/32 to as deep as almost 3/16". It seems to be on the end grain in most all cases with the other 4 sides painted or plain.
the block is about 1 3/4" cubed so the detail is very fine. The only thing I could think of is sandblasting with a photo resist, but I think it's too smooth for that & I can't believe it would have economically feasible if the technology even existed that far back.
The wood seems to be Pine and Basswood with some other species randomly appearing in older sets.
I would like to try makings some - I've newly found this forum, but do a lot of cabinet work & antique repair.
thanks for your help
