Nov. 11, 1957 - Have you already seen me in the latest newsreel? I can tell you, there was quite an excitement. All people of Hahnenklee were up and about. The visitors of the health-resort just threw about with peanuts, but I simply did not care and set down right in front of the tele-objective. One does not have the chance to appear in a newsreel every day hereabouts. The poor little thing had no idea on lens systems and all that appeared on the film was nothing but a chunk of hair - on the other hand our photographer was lucky to shoot this picture of the squirrel.
