"Use only the Herman-McLean Co.'s teas, coffees" and perhaps baking powder, too, as that weathered following line apparently suggests. This wholesaler and retailer of groceries, flour, and feed was established in 1872 by Cleveland-born David C. McLean (no trace has emerged of "Herman"). The company seems to have shuttered in the 1940s, but a renovated Herman-McLean flour and feed outlet, not far from this faded ad, is today home to the brewpub of the Great Lakes Brewing Co.
