Hi John, my friend brought his cards over a couple of days ago so I could look at them again.
One thing that I hadn't noticed the first time was how much they vary in size.
They don't fluoresce under black light so the paper is pre 1950.
The Pafko measures 2 5/16 by between 3 1/2 and 3 9/16
The Sain measures 2 3/16 by a hair bigger than 3 9/16
