Very hard to find vintage brochure from Boller & Chivens, 10 pages, 8.5 x 11 inches. Great older telescope photos! Not dated, if anyone knows a date for this, please let me know! Great condition, just some minor edge-wear. I have only two of these!

Universities; Arizona, Yale, Toronto, Wellesley, Princeton, Colorado, Hawaii
