A mischievous baby in a ruffled dress grins with pure glee as she holds a candy sucker just out of reach of an earnest, fuzzy little puppy — a charming piece of American humor art copyrighted in 1910 by artist V. Colby, whose whimsical child-and-animal illustrations were enormously popular during the Edwardian postcard craze. The phrase "There's a Sucker Born Every Minute," famously attributed to P.T. Barnum, is here rendered entirely innocent and literal, a playful pun that would have delighted recipients of any age. This used example was sent by "Aunt Janis" to a young woman named Eleanor at 5216 Market St., Oakland, California — a real address in what was then a thriving residential district of a city still rebuilding after the 1906 earthquake.
