This is an amazing picture of the Lord's Last Supper. This piece is a puzzle. The table and figures are made of metal and applied to the background. When sold to be I was told that the background was onyx, and the seller was positive about that. I think it's glass with maybe black reverse painting. It's hard to tell without taking the back off. The entire frame is metal, no wood. The frame looks like a mix of white and copper metal. Parts look like it could be a copper wash over some type of base silver, or maybe silver wash over copper. Once again, it's hard to tell. I've never seen anything like this before. I believe it is vintage, and could quite possibly antique. The edge of the metal frame folds over to close up the picture. This part of the metal looks like it could be some grade of silver. Parts even look like they could be sterling, but I've looked and cannot find any marks of any kind. It's kind of heavy, weighing 3 pounds and measuring 16" x 10". Any info on this item or this technique would be much appreciated. Sometimes vintage, sometimes new, but always a bargain.

Although I am not an authority, I do my best to describe items as accurately and honestly as I can. This item is sold "as is," which is in used, but good condition. If you have questions, PLEASE!, ask them before you place your bid and I will respond ASAP. Once a bid is placed, I consider it a binding contract. Buyer pays all costs associated with shipping. (international bidders may have higher shipping costs, and MUST pay with Paypal) Insurance is optional and Buyer's responsibility, so please request it when payment is made. Paypal is my preferred method of payment, but money orders and personal checks are more than welcome. Checks must clear my bank before shipping. I ship at least once a week. Whenever possible, I do combine on shipping to save on costs. However, it is sometimes not wise to pack certain items together, i.e. fragile items and heavy metal items in one box. I'll decide this on a case to case basis. If you think you will be bidding on multiple items, please email me and let me know, because I generally pack up an item as soon as it gets it's first bid. Once it's packed, I rarely unpack a box and repack for combined shipping. I buy at estate sales, yard sales, garage sales, etc. I also use recycled packing materials. Tfore I cannot guarantee that every item will come to you without a smoke smell. I don't expect them to, but it is possible, so keep that in mind when bidding. If I have time, I clean items before I send them. If not, that's your job ;) If you are happy with your product and service, please leave positive feedback, I ALWAYS respond in kind. If t is a problem, please contact me before negative feedback is left. Good luck and Happy Bidding!!!
