Geography Postcards.

It says GEO-47 on upper left corner. Written on 10/26/24 and sent on 11/02/24

I can't find an ID for you.

@ Violet, from Georgia, unfortunately, I fear there is no one here.

What Country was the stamp from?
If not, GEO with three-digit ISO code could be from P.c.U. (here Countries have two-digit ISO code)
Ciao !
