In this image, the pair on the right is the normal scott #1057, perf 10 measures 22.4 X 19.6 mm. The stamp on the left is perf 9.5 measures 22.8 X 19.8. It is engraved printed, not tagged, and the paper is much thicker than either wet print or dry print paper. Has anyone seen this before? Is it a forgery?
