this is an ultra rare US stamp Scott 482A type IA , type III private perforation
I believe this stamp is 1916 2cent Imperf. #482A- Deep Rose- Type IA
same type as type I but with more distinct lines in the overall design and stronger toga lines shading.
Flat Plate- Imperf.- unwatermarked- 1916:
This stamps was printed especially to fill an order by the Schermack Company who then applied there trade mark oblong perforation to their order for the Imperforated 2cent stamp
