This is a striking and detailed engraving from a photograph of an unusual white raven.  White Ravens are not albino animals, lacking all pigments in the feathers and tissues.  They are actually white feathered but otherwise normally colored.  They are not as uncommon as you might think.  Even here in Seattle you can find white crows, relatives of Ravens, in Lincoln Park in West Seattle.  This engraving is done in white Kaolin Clay and framed in light colored solid pine and has both 3M Command Strips and a wire hanger set with wall pads installed.
