Metallic replacement text style label for Atari 2600 cartridge. 

From Atariage, "Atari Text labels were the first major standard that Atari used. These labels are very simple text featuring different colors for different games, on a black background. There is a gray border around the main label and end label." 

The labels are printed on metallic sticker paper. This gives the gray borders and colored text the metallic sheen that captures the look and feel of the originals.

Thanks for looking :)
