E97's or other type?

[Ladder7]

From the beantown find... Have a group of the E97s and all are brutally trimmed. These blank-backs appear to be E97s (but not certain) and similarly hacked (only the three thusfar). Perhaps a notebook cover cutout?
Thankyou, Steve

Vaughn, Tinker and Bresnahan are E98s with blank backs. Very interesting!

Love the borders on the Bres.

The Moore is E97.

Do you know where this collection originated from Steve?

Rob,

From Boston. It was the stash of a college chemistry professor. "Doc Clarence Ropp", born around 1895 I think it was... Didn't even smoke.

I think he spent lunch break rifling through the garbage in Harvard Yard

These all have E97 backs;

i've seen one e98 blank back before...although it factory cut if i remember correctly. the e97s are a bunch of hand-cut beaters...

the professor is all over the place, his e95s are correct...the e98s are blank handcut, and the e97s are regular-backed but hand cut and even a few e97s b/w mixed in.

In the trunk, I'd found an old photo of him, in his work. I think he was working on a polymerization process as a way to protect his cards. Obviously, the gov't funded experiments were a failure.

Im thinking theyre all from the same sheet as well Bob. Maybe the other pieces will turn up.

Steve- interesting find! There was recently an uncut sheet of E97s offered for auction and it appears these cards came from another uncut sheet, albeit crudely cut.
The E98s are a stumper. I have blank backed E93s and E97s but haven't run across a blank backed E94 or E98 before. The blank backed E95s and E96s which circulate are usually from a notebook cover.
If you are interested in selling one of the E98s please let me know, I'd be interested.
Thanks,
tbob
