Victorian Trade Card — Girl Cradling a Bird's Nest with a Robin

A girl in a flower-trimmed straw hat cradles a robin's nest full of pale-blue eggs, while a bird perches on a blossoming branch just above her — a warm, tender image from the golden age of chromolithography, originally printed as a chocolate-company advertising card.

Because it began life as commercial art rather than a greeting card, it's a nice addition for anyone collecting advertising ephemera alongside their postcards.
