Glass picture postcard. This particular piece is created with an original vintage victorian magic lantern slide. Assembled using a variety of textured and/or unusual glass. These photos would have been part of someones private collection or as reference images. I was so intruiged when I found them and love that they can continue thier life as art. Nothing came up on google images when I researched this image... so that can be your job if you'd like to find out where it is and let me know!
