Ever see tacky wax? Even know what it is?
In the ancient days of graphic design BEFORE computers, (yes there was a time when we did things manually)... tacky wax was used to hold graphical elements in place on a mechanical board. The wax was similar to a glue, but allowed repositioning of the type or image. Forms of tacky wax are still used in making stained glass, and other creative arts... even advertising.
