D350-3 Standard Biscuit (E121-like) issue date

[nolemmings]

the true way to tell the date of a set is to find players that were making their FIRST appearance w/ a team in the year of issue (not the last appearance because that could have just been from outdated info or photos)

Yeah, I get that. I just hadn't examined many of the cards to determine first appearances.

Have you established that any player appears in both Holsum Type I and 2 with the same pose? Also, owning but one of each, I note from mine that the Holsum back is oriented differently from type I to type 2, the latter reading top to bottom. Is this always true?

That Strunk analysis seems odd to me. The type 2 card is just a recycled pose from 1917's E135 and friends sets, as are so many of the Holsums and e121 related cards. Why take the time to print an action shot in type 1 and then later replace it with an old, rehashed photo in type 2, as opposed to the other way around? Just musing.
NEVER MIND- I SEE I HAD IT BACKWARDS ON STRUNK
