According to worldchesshof.org :
“He patented his abstracted design in 1954 and had originally intended the set to be sold in his own toy and game factory. However, he later licensed Pacific Games Co. to produce and sell the set when he chose to return to his teaching career. “
The plastic sets are copyrighted 1960, as far as I know. Not sure where you get 1930 from.
Hi all. My preference has always been for non-Staunton sets esp. modern designs. Naturally that would include the Hermann Ohme set. I have seen originals in wood, which are exquisite - but probably very rare, and presumably way beyond what I can afford. That leaves two options: the plastic originals copyrighted 1960 (they come up quite often on eBay) or the Chess Bazaar one.
My question is twofold: a) has anybody got both, and if yes, how accurate is the CB version, and how does it compare to original, aesthetically speaking? b) is CB version not an infringement of copyright?
