I think Mr. Lipset mentions graybacks because the player listing on the back is in a gray ink. That is in the paragraph about E94's that is on page #13 of volume 2 of his Encyclopedia.
E93, E94, E97, and E98 are all quite similar.
E93 has Standard Caramel at the bottom.
E97 has EC Briggs at the bottom.
E94 could have been "anonymous", or could be described by the gray ink on the back.
E98 could also have been "anonymous", or could be described with the "30 players" designation.
Realistically, there are enough anonymous caramel cards, and any distinctive factor would aid in differentiation.
Bert Sugar described E94s as Star Baseball Players, circa 1910. Bert suggested the cards were distributed by George Close Company and Blomes Chocolates.
Mr. Burdick merely listed E94 as "Star Baseball Players"...
So graybacks for the gray ink.
