I have about TWENTY Nielsen custom cut 20x24 stainless steel finish (actually I think they're aluminum) frames. For ease of packing and shipping I will send without glass (buying your own is actually cheaper than the shipping difference!). But if you really need it I can provide you with Tru-Vue Museum Glass (much pricier though). I'd LOVE to sell these as a lot for your exhibition needs - but partial buys are okay. I may give preference to those who need the most frames however. The frames themselves are quite deep (front to back) at almost 1.5". the front lip is strikingly narrow at 1/4". $30 each first come first served. Can be cut down further on your end if you need a custom size.
