Odd Shaped Blotter art is typically vanity blotter art. As far as I know they are all made in Germany. Some are easy to find and cheap others are almost impossible to get nowadays. There are Hexagonal sheets in 2 sizes, Triangle sheets in 2 sizes and then the die cut custom shaped that can come in a variety of sizes. The number of trips indicated for the custom shaped blotter sheets are the number of full triangles because of course there are some smaller pieces at some places. The below examples are the ones I currently have in my collection and as far as I know i’m still missing about 5 designs that were released and documented which are unfortunately out of print and it doesn’t seem like they will be reprinted anytime soon.
