I've seen a number of exhibitions in the last few years, some in major galleries, where photo artists have used stainless steel circular magnets to hang their work . One of the artists was even selling giant Lightjet prints hung this way for over 30 grand each. They were huge pieces and the presentation was surprisingly elegant. You just put a steel screw in the wall and magnet on top of the print corner, about six per print in all.
Does anyone know where you purchase these online? I've found the small ones about 3/8" in diameter but I'm trying to find the larger size that are about 1" in diameter.
