The disclosure is directed to several related forms of PICTURE FRAMES for displaying photographs or similar illustrations. More particularly, the disclosure is directed to picture frames constructed from a single flat die-cut foldable paperboard blank convertible into a three-dimensional picture frame without requiring the use of adhesive, adhesive tape, staples, clips or other fastening materials. This is accomplished by the use of rectangular paperboard panels approximately the size of the photo or other picture to be displayed, with infolding flaps on at least three edges of the panel to engage the edges of the photo to entrap the photo and hold it in place.
