Great info. I concur that Burdick probably just lumped the silks and their ilk together...

When coupled with certain shades or colors on the colored version silks, it may give the appearance that there are more than three different ink colors but, it is only those three. Below you can see the blue, brown and reddish-rust colored inks used on these three different blue colored silks. You can also see the subtle shade differences in the blue colored material used that Ed was mentioning.

Also, these are not printed on silk. In fact, if you view the advertisement on the back of a white version silk it clearly states these are on satin material. See post #5 above. And if you've ever held and felt the material of a white version silk, I'm not so sure you'd call it satin either. Not sure where the description "silk" originally came from and why that stuck as the name for these S-74s. I've always assumed it was from early collectors, like Burdick, lumping these in with other similar collectibles that actually were printed on silk, and just giving them all that same "S" designation that was used in the American Card Catalog.
