If you are curious on how my backglasses were created to replace the broken/messed up backglasses for my 1947 Exhibit Mystery and my 1937 Genco Junior, keep reading!
The files are made using the GNU Image Manipulation Program (GIMP), a free and open source raster image editor.
These are the source images, and may not have been the final that were sent to the printer.
The main thing about my process is that I reprint the viewable image again in reverse for the masking side. I also worked with the printer to find a way to print on a single piece of vinyl, which should resist fading and wear.
Each of these backglasses was color corrected from photos on IPDB and my own remaining glasses by taking an average sample of each color from various areas on the glass and reviewing the images on IPDB.
They are not perfect, by any means, but they turned out quite well compared to the bare sheets of broken glass that were in each game previously.
