Cooke Christmas Card, 1979.
Larry's printing company, Lake Printers (now Lake Media Services), used a state-of-the-art 1/color Heidelberg printing press that could register sheet after sheet perfectly. Paper entered the press hitting 2 head stops and the head stops could be moved incrementally.
The black tree printed first on white paper, then dark blue — but moved ever so slightly off-register to give the effect of snow sitting on the tree limbs.
According to Larry, this technique was the cat's meow!
