TWISTER POSES

Perhaps the finest photograph ever taken of a tornado–certainly at any rate a most unusual one–was obtained by Ira B. Blackstock, a Western railroad executive, at Hardtner, Kansas, on Sunday, June 2, 1929, at about 4:30 p.m. Mr. Blackstock let the windy monster approach as closely as he dared, standing with one foot in the entrance of a cyclone cave while he waited for the right moment to snap the shutter.
