Object Details
- Description
- This unmarked 8" 30°-60°-90° triangle with an open interior is made of two different woods, with a section of darker wood laid between two sections of lighter wood. The dating of other objects from this donor suggests the triangle was made around 1900. Compare to MA.335330. Neither Keuffel & Esser nor the Eugene Dietzgen Company advertised triangles like this one. James W. Queen of Philadelphia did offer walnut or mahogany triangles with a maple inlay, but the firm did not sell the instrument in the 8-inch size.
