I am posting this message for a colleague of mine at the University of Alberta who is looking for ideas or opinions on methods of hanging an exhibition of Old Master Drawings (graphite, charcoal, conte, ink and ink wash). The works of art are already framed in a vareity of sizes, widths and styles of frame. He is looking for information on lighting methods and concerns, and ways of mounting the art on the wall in a secure (eg. can't easily be stolen) but inobtrusive way. Replys can be sent to me directly: [log in to unmask] Thanks!
