US Stamp #1488, N. Copernicus, 8c, 1973, F/VF, NG, NC, Attn: No Gum. Block of 4.

The gum is missing because I had to soak the stamp to remove it from my incorrect stamp storage technique.

ATTN: Soaking the stamps means that in some cases, they did not dry perfectly flat despite my best efforts.

If you want additional pictures, please contact me and I will send.
