An inky webbed-foot print made by the young
Louie Trumpeter or The Ugly Duckling when rubber-stamping his "John
Hancock" onto an important document. Can also loosely refer to the line of cute little footprints left by a baby
swan as he waddles along the shore.
In "Corny Concerto", The Ugly Duckling encounters two separate "unique codes/representations of oneself" situations --- first, the rough raucous "QUAACCKKK, QUAACCKKK!" sound of his "audible signature" gratingly and obviously differentiates him from
Mama Swan's "truly biological" trio's melodically-trilling cygnetures, and then the furiously-outraged
Mama Swan leaves her own "signature" on The Ugly Duckling's behind when she tempestuously bunts him away off back up the stream.
