This listing is for the exact little pieces of sidewalk concrete shown in the images. These pieces of concrete were taken from the old sidewalk in front of 575 Castro St where Harvey Milk had his camera shop & campaign headquarters. When the city was replacing the sidewalk in 2014 the owner of a local shop collected some concrete from that exact address and I got a small amount of this concrete from him, buying up all he had. I've researched and to the best of my knowledge no one else collected any of this! I vouch for the authenticity of these little relics of famous San Francisco real estate! Comes in a gift box with a certificate of authenticity informational card to keep with it. May you feel the spirit and power of the millions of queers who have blessed this cement with their feet while walking, dancing, and marching. I only have a few dozen pieces of this sacred Castro concrete left and when they're gone, they're gone!
