The product is a set of vintage square or diamond shaped ( when hung)  plaques featuring religious symbols such as Jesus, Crown of Thorns, and Mary. Made of blue beveled mirror glass with a Christian theme, these plaques are perfect for collectors of religious memorabilia. The craftsmanship and origin of the product are not specified, but it is clear that these plaques are a unique and meaningful addition to any religious decor collection.  The sides measure 6 inches and just a little over 8 inches top to bottom from the points.  Really nice pair, the shiny blue glass rather covers the dark spots when hung..   
These square blue mirror Jesus and Mary plaques have been hanging in my office the better part of 20 yrs.  It is probable that they were hanging in someone's home before I got them... In good condition and the mirror background shows some darkening in spots as aged mirrors tend to do.  The faces are plastic,  usually referred to as celluloid from the 1940s to early 50s that I believe these are from.  .  these hang at an angle, so rather like diamond shape when hung.  Felt padding on the back with handing loop also there.  See pictures as they are better than my description.  Buyer to pay GrAdv shipping, continental USA only.  See my other listings and my Ebay store Vintagejean24  Email questions.
