发明名称 Assembly to demonstrate and teach the game of bridge
摘要 The assembly is intended to sequentially reveal four hands of bridge starting from the dealer's hand to and including the right side opponent's hand. As revealed, the hands are represented on an image reproducing surface such as an overhead projector. To arrive at this, there is provided a transparent sheet displaying four pre-determined bridge hands and a series of overlying transparent sheets successively concealing one to four hands of bridge. This assembly visually illustrates in an inter-active learning situation, and in an uninterrupted way, the appropriate bidding sequence and the play of each of the four hands of contract bridge, that is fifty-two cards.
