Four-up Prints for Strip Sets

I have several four-up prints of John Willie photographs–four 4×5 inch prints on a single 8×10 sheet which were meant to be cut apart. I also have several strip set four-up prints. Strip sets normally were sold in sets of 12 in the 1950s when these photographs were shot. The 12 photographs would be printed on three four-up sheets. I am posting images of the four-up sheets and selected images from those sheets.
