Viking ship 1m. blue without frame as vertical pair from the upper left sheet corner, in addition single black proof of the frame only on silk paper.  In the picture the single on silk paper is placed upon the vertical pair G5, to illustrate how the proofs on silk paper were used to verify the correct positioning of the two stones with the two colors, crease through G3, otherwise a fine and very interesting assembly (Hurt/Ojaste G5 and G3)
