I enjoyed David T. Alexander's article about Art Kagin, and I see that he noted how Art was a big mover of coin boards during the 1930s out of the Hollinbeck coin shops. I'm attaching photos of coin boards in my collection that were rubber stamped by the Omaha and Des Moines stores before sale. This was a way of reminding buyers where to bring their collections when it was time to sell, and it also served as free advertising to potential new customers who viewed their friends' coin boards. I have a few examples of adhesive address labels applied by the Omaha store, but these lack the charm of the rubber stamps.

Also attached is a photo from my coin board book. It's a portrait of Art in one of the shops that also shows a partially filled coin board in the background.
