Abstract: A key chain with decorative function which has a miniature photo frame connected to its one end and in a size similar to that suitable for the usual decorative plate of a key chain, and on back of the photo frame, a clamp is provided to allow the key ring of the key chain to snap in and thereby form a support permitting the photo frame to uprightly or crossly stand on a table or desk top as a decoration. Pictures preferred by the user may be inserted into the photo frame through a movable clear sheet at the front of the frame. When the key ring is detached from the clamp, the key chain is served as a general key chain.
