Puzzle, Gilbert Conjuring Rings


This disentanglement puzzle consists of two intertwined metal rings. A green paper card gives instructions on how to separate them. A mark on the card reads: Gilbert Conjuring Rings. Another mark reads: THE A. C. GILBERT COMPANY NEW HAVEN, CONN., U. S. A. Another mark reads: M 104 No. 11 4-17. Assuming M 104 is the model number and 4-17 the date of the card, this object is slightly earlier than the conjuring rings shown in the 1920 catalog cited below.
