Question re: S21 vs. S22 tobacco silks

[BradH]

Hello-
I have been collecting the S22 Murad college tobacco silks for a few years and love the way they look in frames in my office and at home. I concentrate on Purdue athletes and any Big Ten baseball, football or hockey players I can get. So far I have about 25 total silks.

Yesterday I received a Purdue baseball pitcher (pictured below) that I purchased off eBay. It was advertised as an S22 silk, which measures approximately 3-1/2 x 5-1/2 inches. When it arrived I noticed it is the larger S21 version, which measures about 5 x 7. I don't really mind, and I'm sure the seller made an honset mistake, it just doesn't really fit with my other framed Big Ten baseball players.

This is my first S21 - does anyone know what the approximate ratio is for these compared to S22s, as far as rarity, print quantities, etc, and are they harder to acquire than the S22s?

Thanks for any input or thoughts you can provide.
