Frame for Printing Post Cards from Negatives
As I desired to print only a portion of some of my 5 by 7-in. plates on post cards and the part wanted was near the edge of the plate, I cut out the printing frame, as shown at A in the sketch, to accommodate that part of the card I reserved for a margin. This permitted the card to be placed in the frame without making a bend.—Contributed by J. H. Maysilles, Rochelle, Ill.
