RHODESIA 1966 (TRIAL) 10S GUINEAFOWL IMPRINT BLOCK ON THINNER PAPER
10s Guineafowl imprint block x 8 from scarce Mardon trial printing on JH3 (thinner) paper. Superb proving piece as text of trial imprint is large while that of normal is small. Fine unmounted mint. SG406var; SC235avar; SACC154a
Note: a total of 129 panes of 60 stamps were printed on trial JH3 0.09 mm thickness paper. The normal printing is on JH4 0.12 mm thickness paper. The printer's imprint on the bottom margin of trial panes is large compared to the smaller imprint on regularly issued panes. Further, the trial JH3 paper is more translucent than JH4 paper – this is particularly apparent when looking at the back of stamps as the design filters through to a greater extent on the JH3 paper
