Hal LewisBeing that it is a Postcard...
I can tell you for sure that there are a lot of folks who do NOT consider it his "true rookie card."
Some folks will never consider a Postcard to be the same as a "real" baseball card.
I don't know if anyone would consider a Postcard featuring Mickey Mantle in 1965 to be a "real" baseball card, so I guess the same standard applies to something from 1907.
Personally, I think the Postcards are COOLER when they are USED.
I would love to have a Cobb Postcard from that set that was postmarked in 1907 with a cool old message written on the back!!
