A while back I was fortunate enough to buy a box with penny red stamps. The SG 43 1864 issue with letters on all 4 corners. it was very cheap and there were 1875 stamps.
I finished most of the work on these stamps and also tried to make an alfabet sheet. A to L Horizontally an A to T vertically.
That would take 240 letter combinations. I did not think I would get there
And I didn't. final result: 239 out of 240.
Still I am very happy with this result.
