Publisher's Synopsis
Excerpt from Eye Defects: How to Detect and Correct Them
The business of the Spencer Optical Manufacturing Com pany, established nearly a third of a century ago, has grown rapidly and steadily since, and owes its success to the business principles upon which it was founded, fair and square dealing, and the best goods at the lowest prices. On another page we give an illustration of the Company's works at Newark, one of the largest of its kind in the world, containing square feet of ?oor room, the most improved machinery, and a capacity for 600 skilled workmen.
Our interest has always been in elevating the standard of the trade.
