This photo of the DNA Lounge roof being constructed was taken one hundred years ago, on this day in 1923:
And pictured in this slightly earlier photo is the fellow who built this building, Dave Lerer, who was our current landlord's grandfather. He's the one in the dapper waistcoat.
So that was 54 years as a warehouse and foundry; then 8 years as a bar; then 38 years as DNA Lounge!
