Gibbons Stamp Monthly

Plot

Included in this month’s GSM, Andrew Mortlock discusses the surface-printed stamps of Queensland with a focus on the 1d. value, which was produced in the largest numbers, has the greatest number of designs and was used for a number of rouletting and perforation experiments and John Roe continues his study of the 1883–84 Lilacs and Greens Unified series with an examination of the imprimaturs, ‘SPECIMEN’ overprints, imperforates and colour trials for the issue.
