12c Black, Plate 3, Double Frameline at Right (36B var). Intense shade and impression which clearly shows the variety, neat red grid cancel, wide margins, Very Fine and choice example of this variety, according to the Neinken pamphlet on the 12c stamp, "These extra side line varieties are the result of vertical lines ruled from the top to the bottom of the plate, and while not always continuous, they generally are found extending the full length of the stamp. It is believed that each position in the third vertical row had an extra line to the right of the right outside frame line, and each position in the fourth vertical row had an extra line to the left of the left outside frame line. Thus two extra vertical lines were ruled between the 3rd and 4th vertical rows. Between the 7th and 8th vertical rows of the left pane is a single line, which we believe runs from the top to the bottom of the plate.", with 1983 and 1998 P.F. certificates
