Abstract
Disclosed is a frameless picture support in which a picture is placed between a cover plate and a backing plate fixed together by spring clips having hooks going around the edges of the support and back parts behind the support. The back parts are kept in position behind the backing plate by headed pins with the bending of arch-like parts of the clips. The clips have steps across their widths for locking them in place against the pins.
