This is the Richard Serra 50 Year Award PSA Grade 10. It exactly mirror's his first card that was released in 1968. 50 years in the game is a significant achievement and it warranted the release of 10 of these rare cards. All but one has been found and there is already only one GM MT 10. It has been trophied in inch thick lucite and fastened with brass hardware. Each Card sits upon a brass pin that connects to a wall mount that is also fastened with brass hardware. Its iconic design, signature details and its rarity make it a truly remarkable piece of art popular culture.
