Lobby of the Rincon Center Postal Annex. The restored WPA 27-panel mural was painted by Russian artist Anton Refregier. The murals were controversial with social conservatives, because of their portrayals of the waterfront strike and Sand Lot Riots (anti-Chinese uprisings). Ultimately, citizens and artists defeated critics who wanted the murals taken down.
You can find additional collections of WPA murals at Coit Tower, the Beach Chalet.
