These are vintage leather "wallets" that differ in size, ranging in size from about 4.75 - 6.75". One is a Pierre Cardin.
For all of these, the leather is VERY soft and they are in good condition. I assume that the larger sizes were also used for passports or VISAs because my uncle and cousin (who they belonged to) lived part of the year in the U.S. and part of the year in Europe. These are from a non-smoking home.
I am asking $15 each but, if you wanted them all, I would sell them for $75.
This is what you can see in the photos by NUMBERs that I added to each one with a little post it except for the last 3 photos that I didn't number:
1 -- Dark brown leather. Unmarked that I can find. 4.5 x 6.5 inches.
2 -- Black leather marked Parri, Made in Florence. 4.5. x 7 inches. This has the initials CH on it but this can easily be marked over with a permanent black marker unless your initials happen to be CH! LOL
3 -- Black leather with an enclosure that says Zulassung. This is German and likely has nothing to do with the wallet but it is in there. It also has the initials WK which can be blacked out unless they are your initials too. 5 x 6.75".
4 -- Black leather. No markings. 4.75 x 6.75"
There are 2 different wallets (more traditional size) in the last 3 photos. The last 2 photos are of the Pierre Cardin.
