OK, Greg - I have some news for you. I have located a Federated Banknote sample stock certificate AND a set of De La Rue sample stocks!
I wish the images had better resolution. It is included in a promotional booklet from Federated in 1966.
Here's a "how to" sample from De La Rue. These sell for $90/each. Circa 1990, available in Blue, Colbalt, AquaMarine, Gold, Lavender, Orange, Brick, Rose, Brown, and Green.
I have done some soul searching & came to the conclusion there are compelling reasons to include stock certificates in the catalogs - eBook & book form. Of prime importance, yet another fiscal document, so why not?
I am left with one conundrum. The upcoming book on test and promotional notes of North America will certainly include Federated. Even though it is a foreign owned firm (TDLR), it had offices in New York and Philadelphia and only had business in the states. Thomas De La Rue - what to do here? The stock certificates were for US consumption only. 1) Include ALL materials 2) Include only stock certificates & those test/promotional items for US only use 3) Not include TDLR at all. I am inclined to not include any TDLR at this point.
Both of those are interesting items! Have not seen them before. I'd be curious to hear your rationale for adding promotional stocks/bonds to the catalog. I have no preference either way, although I do like them personally. You are welcome to quarry any images from this thread that you might want to use. You'll need to define the difference between promotional specimens and standard specimens.
My take on De La Rue in the North American catalog would be to only include items used in the U.S. or leave them out. And (unpopular opinion follows) that would go for Bradbury-Wilkinson -- despite being owned by ABNC for a time, they were always a European entity and their imprint never appeared in North America that I'm aware of.
