The holder is of the type described in U.S. Pat. No. 4,056,296 and comprises a plastic body which is molded as an integral unit and comprises two side sections which are connected together by a hinge section so that they can be swung toward and away from one another. The improvement comprises document mounting pins carried by one side section and engageable by the other side section, one or more of the pins being adjustbly mounted on the one side and movable toward and away from the other pins. Manually releasable locking means are provided for locking the two side sections together so as to captivate documents which are mounted on the pins.
