Sapolio-lic" : selections from E.M.S. "Pinafore" / presented by Enoch Morgan's Sons Co.
The pattern
This still is filed under Iconic figure claim.
Define
A single figure, drawn, silhouetted, or posed, is the whole claim. You can read it across a street.
Mechanism
Compression into a body. The figure is not decoration. It is the sentence. Distance-legibility is the test.
Verdict
Poster scale, outdoor, packaging at a glance
Why it works
It uses entertainment and popular culture to deliver an ad. People who loved H.M.S. Pinafore would find the parodies amusing and share them, effectively memorizing the jingles and brand name. The interspersed pages of plain copy do the heavy lifting of selling the product's actual uses.
Steal this when
When there is a massive cultural phenomenon you can playfully hijack or parody to make your advertising entertaining and memorable.
