Honus Wagner 350 subjects back ?
 

I seen a Honus Wagner with 350 subjects instead of 150 on a Sweet Caporal back. Is there anyway possible way that this is an authentic card? There are only 3 Piedmont's, maybe this is even more rare?

Unless it is re-backed, no.

There are at least several thousand reprints of Wagner with impossible backs.

Was affraid of that. Been looking for images on google all day.

Don't waste your time.
