Carborundum etching with extensive handcolouring. Only the deep "sculptured" structure and the 2 letters AB + the light blue background behind the horisontal green are printed. All other colours - included the red triangle seems to be indiviudally handpainted with gouache. Signed in pencil and numbered in numbered in 90 copies with pencil - the numbering being followed by a B - indicating that there is also an identical version where the broad wide horisontal stripe is blue. Whether that means that the 90 copies are divided in two versions of each 45 copies or there are 2 editions of 90 copies is unknown. In perfect condition - no damages.
