Looking for Rubber Stamps for Composing Diagrams

How much did they cost?
Each or for the whole set?
So the whole set of photopolymer board and chess piece stamps was around $20 USD for me in 2019. You can either mount them on wood or acrylic or ask her to mount them for you. That will add to the cost.

I found a custom rubber stamp store in NYC and had them make me a set that they had on file that was originally commissioned by William James Lombardy, who lived in my neighborhood. I added the Black/White to move stamps to the set. Bought from Casey Rubber Stamps.

That set looks excellent. Good idea about the white to move / black to move stamps.

Where'd you get these stamp pieces and which mark is which? Be curious to see what the full set looks like.
When I had access to a laser engraving machine, I made the board and symbols in Corel Draw and sent them to the machine. Also made these wooden pieces using Corel Draw.
Something like the old Chess Type Stamping Outfit
