The Great T206 Back Stamp Project

It appears that multiple agents from the Saturday Evening Post had the same type of stamp with their own names on them and would stamp T206s with them.  So far we have stamps from the following agents:

1. John Anderson
2. John Greb
3. George Neal
4. Stanton J. Breech
5. Harold Crozier
6. Howe McCormick
7. Chauncy Enery
8. Chris K. Trane
9. Edward N. Moore
10. Robert M.
11. Lesesne McCallister
12. Sam Lennox
13. Robert Wallace Jr.

Let's see how many others we can uncover.
