Between 1924 and 1927, Timmins produced a number of ad illustrations for ILG Electric Ventilating Co. Eight ads from this series are presented below. The first, from 1924, bears the TY (Young & Timmins studio) symbol. The remaining ads produced by Timmins do not have the TY symbol, but it stands to reason that they came from Young & Timmins. Other ILG ad illustrations not done by Timmins in 1928-29 do have the TY symbol, and the ads have lettering and layout that is essentially identical to the ones done by Timmins. Regardless, Harry’s work for ILG demonstrates his ability to integrate color, figures, kitchen or office scenes, and various background elements into a pleasing and compelling whole.
