Description
I found this board on Internet, on the Elliott Avedon Museum site. Here is what the page states:

The photograph above on the right is one of the latter editions of Reversi under the name "Chinese Friends". This copy was donated to the Museum in 1971, although it had been manufactured and sold for a number of years before that by a U.S. company - World Wide Games, Delaware, Ohio. The board is 29.5cm square and .5cm thick. The 58 counters are made of cardboard, printed with red on one side and black on the "reverse".

I have a question: 58 counters?
