Define it.

1948-55 Bowman sets are sports cards.
1951-59 Topps sets are sports cards.
The 1959 Fleer Ted Williams set is full of sports cards.

What about food and beverage cards? Are they "cards"?
Kahns Wieners, Morrel Meats, Hires Root Beer, Swift Meats, Rodeo Meats, Red Man tobacco, Johnston Cookies Braves, etc.

What about the ones that have blank backs like the 1959 Bazooka set?
Does a "card" have to have something written on the back of it to be considered a card?

Does a "card" have to be within a certain size?

Wilson Franks and Red Hearts have backs with stats, seems like a sports card to me.

The "Standard Catalog of Vintage Baseball Cards" book has 288 separate listings of 1950s sets/items.

I'm just a collector trying to figure things out.

Any help would be appreciated...
