Thoughts on t206 Stahl - No Ink
 

Attachment 345156 Maybe hard to tell from pic, but card seems to be missing red ink (and white on uniform and cap). Also, appears from faint "Boston," that the "B", which is in block letters on a typical card, seems to have a "tail" on the lower left similar to the "B" on the Doves uniforms. Any thoughts? Seen a similar no ink Stahl before?

Is there a glue stain on the back? Looks like a regular card to me. Red ink tends to fade first and if there was an adhesive on the back it tends to pull red ink from the front.

clean back
 

no stains, residues, discolorations, etc.

It's just sunned/faded.

Red absorbs UV light much more than other colors and therefore fades the fastest.
