Timmins did ad illustrations for Sellers Kitchen Cabinets from 1922 through 1924.  Harry’s 1922 Sellers work was done for Bertsch, and an example appears on that page.  The 1923 and 1924 Sellers ads were probably done within Y&T, but none are signed.  I find the full color 1923+ Sellers ads to be lovely, and indicative of Harry’s full capabilities during this period.  Harry combines clean layout, attention to detail, and excellent figurative work to create a compelling vision – all for an ad subject that might easily be boring, and which had been until this series.
