We didn't do the original sign, but we did have to replace the push-throughs on this one. That's a real trick when you don't have the original artwork! Anyway, the main copy is just Show-Through letters (where the aluminum face has been cut through and is backed by translucent acrylic with back-lighting. The Logo on the left is a 3/8"-thick Translucent Blue Acrylic Push-Through. The whole Logo is one piece with the areas between the squares milled down allowing the squares to push through the Aluminum Face.
