Oke everyone, I need your insights !! I recently picked-up a cool Glavine printing plate. Being a Glavine collector I assumed that whatever Printing plate I come across I still need for my collection. So when the package arrived I was excited and loaded my spreadsheet. Interestingly enough, my speadsheet indicated I already owned it. Of course I checked right away and yes, I already owned a copy, leaving me with 2 Cyan Printing Plates like the one below.
Any thoughts on how this is possible ? I always figured these were 1/1s ?
