Adolfo Biener

The earliest known postmark on a postcard published by Adolfo Biener is 1915.  Apart from the marking, Biener's early cards are almost indistinguishable in subject matter and printing style from those of Alberto Valdeveallano.   Archaeological sites, earthquake ruins and portraits predominate.

Unlike Valdeavellano, whose only use of color was in solid or rainbow tones, Biener in the 1920s began publishing a line of postcards printed by a full color lithographic process.  The differences can be noted in the middle example above, as well as in the examples below. These color cards have white borders, and later ones have deckle, or uneven, edges to their white borders.
