The error border resembles that of the ½p Castletown stamp, [[IM-SG-12|SG 12]]. The catalogue also records intermediate shades, but excludes those from its error listings.<ref name="SG2022" />

The relevant printing is (c), dated 16 April 1974. This is the printing date recorded by the catalogue; no separate first day of sale is given for the error. It belongs to a later printing than the stamps originally available for the 5 July 1973 first day cover.<ref name="SG2022" />

The design is credited to J. Nicholson. Courvoisier printed the stamp by [[wikipedia:en:Photogravure|photogravure]] in multiple colours on granite paper without a watermark. Perforation is 11½, and sheets contain 50 stamps (5 × 10).<ref name="SG2022" />

== Withdrawal ==

The catalogue records general withdrawal of the issue on 31 December 1978. The 3p value in booklets remained on sale until 15 May 1979. Those later arrangements concern the denomination; the catalogue does not establish continued availability of this error in booklets. These are withdrawal-from-sale dates; the cited entry does not give a date of postal invalidation.<ref name="SG2022" />
