AK47 1 Silver
From The Giant: The Definitive Obey Giant Site
It has been confirmed that Shepard Fairey randomly dropped silver paper into several print runs during this timeframe. Only one copy of AK47 1 Silver is known to exist. Run size information is for the complete AK47 1 run and does not differentiate between variations. The only other currently known silver prints are AK47 2 Silver, KISS Silver, and Obey Van AP (Silver).
