If you were serious about picking up artist Jason Chan's Left 4 Dead 4 Kids print (not actual video game fan art, mind you) now's your chance. Prints are available for purchase.
Chan's "Zombie Playground" is available in physical form in one of three size flavors: 13" by 19", 18" by 24", or 24" by 36" with prices ranging from $24.99 USD to $80 USD plus shipping. Not cheap, but similarly not outrageous.
Go on. Stimulate the economy!
