India Ivory Company did not make the sets themselves. Rather the one example I have found looks like a Baby Grand crystal set made by the Beaver Machine & Tool Co from New Jersey in a faux ivory case.1
Their core businees was Celluloid Buttons and Novelty manufacturing. Incorporated in 1920 with a $25,000 capital, their President and Secretary was Joseph Zitowitz with Morris Hollander Vice President and Isadore P Greengus Treasurer. 2 They were located at 238 Thurbers Avenue through 1925 3.
In 1922, The company increased its facilities at 163 Thurber Ave and nearly doubled the numberof girls it employed. 5
In 1922 India Ivory Company is listed as being one of the unsecured creditors of the Bartlett Manufacturing Company, dealers in clocks, owing them $1,770 of $2,366.61 which partially caused them to go into bankruptcy. 4
