This was one of our earliest pieces, however resided for a rather long time in the postal system (delivered a couple months late). The post card rate being twenty cents, and twenty one-cent stamps making a nice 4X5 rectangle, Dennis sent off a sheet of postage with an address on the blank side (does this count as cancelling the stamps?). This was also the first piece we had processed by the nixie division. What an honor! What a joy!
