I found a second example of the Denvers version from the LOTG auction last year:

It does look like a ball may be faintly visible on that example -- so perhaps my card is the same pose as 419-3 but the ball is just too faint to be seen.
But then there is still the issue of the wavy grass at the bottom of my Denver card (and the Denver card in the LOTG auction) which is not present on the OJ Bible and eBay Brooklyn examples of 419-3 . . . .
Seems to me when the team plate was changed from Brooklyn to Denver there was a (not 100% successful) attempt to remove the ball while at the same time adding grassy brushstrokes at the bottom. Thoughts?
