Crate labels were the packaging art of the early export trade, designed to catch a buyer's eye at a distance and signal quality before the product was ever tasted. Spanish citrus labels, produced from roughly the 1920s through the 1960s, are among the most collectible: printers in Valencia and surrounding regions turned out bold, flat-color designs at a scale and consistency that made them a minor golden age of commercial illustration. The period originals from this tradition hold up as graphic art on their own terms.
