Note: Most of the hardware & salvage items I'm listing came from an amazing hardware surplus store in lower Manhattan called Alexander's Hardware. It was a legendary 4 story warehouse full of the most extraordinary collection of antique hardware and bits and pieces of the strangest surplus stuff. Along with hundreds of NYC artists, I was friends with Arty, the wonderful wonderful owner and spent many an hour combing through his warehouse for these items, many of which I've used in my work. I feel certain that Arty would enjoy knowing I am passing these treasures along to other artists. He was as special as all his special odd and curious things and he is greatly missed. A tip of the hat to you, Dear Artie!!
