Johnny Bench - Real? Stamp?
 

I recently picked up a '77 Topps set and found this on the back of the Bench card. Was hoping for opinions on authenticity and whether it's a stamp. I initially thought it was a stamp because it doesn't necessarily look like live ink and I don't see darker areas where the lines overlap, but my knowledge on autos is very limited and I'm not sure. Thanks very much in advance.
