I have only purchased 1 card with a stamp on it and quickly sold it to a collector of that particular stamp. For the life of me I can't remember the exact stamp but as I recall it was a LARGE single letter, old english style font.. argh. Do specific stamps or overprints demand a premium??
If the letter is an "F" it's a stamp I have seen on T206's. Some people believe they could be from the collection of F. Scott Fitzgerald.

***** Of course these were older cards and were BLACK letters in Old English format....just maybe something like this was done elsewhere is all im saying????
