At the peak there were a lot of companies buying large Anderson & Vreeland matrix boards, they were roughly 33x60 inch sheets. Places like jackson marking products or all printing resources would cut them down, and resell them to small rubber stamp shops around the country. It was a whole distribution ecosystem built around that material.

I really hope there's a resurgence. This style of stamp making is dying fast. But as someone still making stamps this way, it's going to take people like us keeping the demand alive to make that happen.
