I purchased the film in 2017 or early 2018, so it is older stock. I have used four of the five rolls of the 120 pro-pack, but this is the only shot that I noticed any print-through on. It says 06/2017 on the bottom of the pack and what is possibly a batch number of 0971 002. I'll have to shoot the last roll soon and have a careful look as I scan for more "ghosts"...
