While the investment hobby of collecting baseball cards turned out to be about as profitable as... well... collecting '90s comic books, Baseball Card Vandals (Warning: Link includes some hilarious NSFW drawings) has pioneered a fantastic use of all those worthless cards: turning them into gloriously juvenile and pun-filled works of art on Tumblr. Thanks to blend of equally crude and deft cartooning from the site's curators and users, you don't even need to be a huge baseball fan to appreciate the pop culture jokes on the site. The best part? There's two new vandalized cards to chuckle over every day on the site. Hit the jump for a look at a few of our favorites. Just don't blame us if you wind up digging through your attic/basement/garbage for cards to deface with Sharpies.
