 # Finding Artwork
 
-Perhaps the most challenging aspect to making a working backglass is finding good artwork. The best possible art is a direct scan of the backglass but that is not always possible. There are backglass images that can be found online but it takes a fair amount of time to clean these up and remove any artifact from them. Another possibility is to get artwork online and use that as a basis for a total redraw.

-To block the passage of light through the backglass we need to make a thickness map layer. This layer consists of pure white `(255,255,255)` for the areas that are opaque and pure black `(0,0,0)` for the areas that are transparent. If you have physical access to the backglass then you can scan the backside to get this mask. Otherwise, you'll have to trace what's visible on the front, and try to reconstruct elements that aren't.

 Elements that aren't visible are often scores that aren't part of the actual artwork. In this case, your best bet is to find a similar font to the original art and eyeball where it goes. A helpful site is [WhatTheFont](https://www.myfonts.com/WhatTheFont/), which helps you identify the font in an image.
