ABSTRACT:
A display easel for placement on a desk or table functions as an erasable writing board, an easel to hold display placards, and a loose paper clipboard. The loose papers are held to the display easel by a self-adjusting clamp mechanism which automatically adjusts itself to the thickness of the paper pad and grips the papers to be held. The clamp mechanism comprises a cylindrical rod that slides up and down in a slot within a housing that receives the pad of loose papers. The pad is held fast to the display board by the cylindrical rod. The cylindrical rod slides up and down the housing, as needed, to accommodate the thickness of the pad.
