Lucidview 6939
The Auction Leprechaun (who bestows the luck-of-the-lot) has bequeathed 16x 2-pocket pages for covers less than 9x19cm (4x7-1/2", y'all) each.
They were in a binder marked "Westminster Collectors Society", who might be these guys:
https://www.westminstercollection.com/(Of course, they might have made their way to that binder from somewhere else.)
The only reference a quick google turned-up was to these same pages being sold in binders marked "Fleetwood".
Unlike the other pocket pages in the same auction lot, these seem to have suffered with time; they are grayish, a bit wrinkly and, in an instance or two, stuck to the covers within.
I am wondering if these are made from the dreaded plasticized vinyl.
They are embossed "LUCIDIVEW 6939".
I look forward to learning.
Cheers,
