Have you seen any of these "missing cards"?

[Howe’s Hunter]

Just trying to keep my database updated on cards I know exist with Howe's stamp on the back, but have no idea where they are now.

Also on the list of missing and whereabouts unknown are the following, which I don't have scans for:

Ames/Glove–Piedmont
Birmingham–Piedmont
Covaleski–Piedmont
Elberfeld/N.Y. Amer–Piedmont
Warhop–Piedmont
Willis/batting–Piedmont

and a Cobb/green portrait/Piedmont that was in a GAI 30 holder about seven years ago. Would have come from a dealer in the New York area, who also attended shows in Canada. My guess is that card may have been freed from its GAI holder and now resides in something else.

Not in a position to purchase/trade for any of these now, but just wanted to throw this on the board and see if I could track any of the missing 23.

Thanks to board members who have let me know they are the current owners of 10 others.

Thanks to all for help in my strange quest.
