1941 Print Ophthalmograph Eye Movements Herbert Gehr Columbia University FZ7 Poster Images including the Mark XLVIIThis is an original 1941 halftone print of a man using an ophthalmograph at Columbia University's Guidance Laboratory. The caption writes, "If a subject scores low on visual tests but gives other signs of intelligence, his trouble may be reading difficulty traceable to eye defects. The ophthalmograph finds out. Good occupational guidance explores all such possibilities." Photography by Herbert Gehr. CONDITION This 70+ year old Item is rated Near Mint
