Bricks by the Bay is this weekend, and those attending are starting to put up some of what they'll be bringing. V&A Steamworks will be selling stovepipe hats in black and white and some with printed bands as well. They will be selling for $4 USD each, or three hats for $10 USD.
Not going to be in Northern California this weekend? No worries. It sounds like the hats will be available to the general public soon.
