Cinema Television magazine ad. from 1952

Fair use rationale
Fair use claimed in the Monoscope article because:
 * no free alternative photo of a monoscope tube is available to illustrate the article.
 * it is a very low resolution scan of an old magazine advertisement - 52 KB.
 * it does not detract from the value of the text, or the copyright holder's ability to make further profit from it, as it is not a current advertisement, being over 50 years old.
 * The company Cintel International Ltd (originally named Cinema Television) has not manufactured cathode-ray tubes for many years and this makes the advertisement of historical interest.
