Label, "H. J. Heinz Brand Tomato Ketchup," circa 1900

Manufacturers of similar products sought ways to make their companies' goods stand out on store shelves. Some companies established a uniform label design for their multi-product offerings -- a strategy which helped customers distinguish one brand over another. H.J. Heinz products were identified by the famous Heinz pickle and signature "keystone" logo. These design features are still found on Heinz products today.
