This looks just like an antique blotter with a tray stand, of the kind they used
years ago, when they wrote with feather quills dipped in liquid ink in a glass
pot. This one was used be a clever counterfeiter, and some of the printing ink
has soaked into the blotter, permitting you to print a bill or two! Just place a
piece of blank paper on the tray, and run the stamper over it, and it is printed
into a genuine bill.
