This allows for a glass (not supplied) to be placed on center of tray and covered with a silk (not supplied) and when uncovered it is seen that a card has appeared inside the glass!  This is made for Bridge Size cards.  Made of wood with painted design measuring 10 3/8" wide to the handles x 6 3/4" deep and only 1/2" thick.  Several ideas for use are given in the 3 pages of instructions.  Condition tray has slight warp but working is not affected, overall very good.
