There are times when you get to do something that’s, well, so artistic and so darn useful all at the same time, that you just shake your head and only hope you get to do it again someday. In honor of the Oklahoma Centennial and the opening of the Collecting Oklahoma show at the Sam Noble Oklahoma Museum of Natural History, there will be a special stamp cancellation, designed by yours truly (although I did not design the cute little dino stamp above and really wish I had) and hand-cancelled at the show opening by U.S. Postal Service staff on Saturday, June 16th. I will also be there to sign the cancellations. Read about it here. Come on down and bring your bills!
