Oscar Reutersvärd Postage Stamps
In the 1980’s, Oscar Reutersvärd (the father of the impossible figure) was honored in Sweden with the release of three postage stamps featuring his impossible art. These items were not in circulation for very long and have since become sought after collectibles. Below is one of the stamps that features a twisted figure that bends in an impossible manner.
The other two postage stamps featuring impossible designs can be seen in the full post below.
