The Present Era of Baseball Cards
Many different companies began issuing baseball cards during the 1910-1915 era.  Cards were issued with colored borders, some red, others green or gold.  Candy companies issued cards with their penny caramel candy and gum.  Cards from this era are an important addition to a fine collection although they are much more difficult to find and are about three times more expensive than the tobacco companies cards.
During the years just before and after World War I baseball cards were not issued with either candy or tobacco, but were sold in strips.  These strip cards were of low quality on cheap paper and of inferior color.  However, almost all of the baseball stars of the era appeared on these cards such as: Ty Cobb, Tris Speaker, Babe Ruth, Rogers Hornsby, and Walter Johnson.  Collecting these sets can be highly challenging and enjoyable, moreover, they are fairly inexpensive.*
