Good evening, I've recently acquired this unknown card of Mr. Cobb and need some help with the identification/history.
Here are some high res scans as well as camera images to see the finish/surface.

The card presents an image of Cobb which looks identical to that used on cards of the M101-6(trimmed) and the ice cream issue of the late 1920s. It contains the hat logo so can probably rule out the ice cream issues, but the tint is slightly different then the m101-6.
The size most likely confirms it's neither of these issues as it's slightly larger than a standard t206 issue, whereas the m101-6 are slightly larger even taking into account this potentially trimmed state
The material for the base seems to be around the same thickness of a t206, fairly crude to the touch. The front image boasts a brilliant shine as seen in the images, this layer seems to be quite thin as the edges and corners do show slight chipping.
If any leads or possible identifications (good or bad news!) are welcome, thank you!
