Sold out

A very fine NH complete $1 booklet, containing 4 panes of of 5 plus label of the 6c stamps from the 1970 Famous Australians issue, printed on Helecon coated paper. The booklet cover bears a small black vertical counting mark, and the interleaving pages are all hibrite under UV.

    The Australian equivalent of tagging is called Helecon, which is a chemical in the zinc sulphide group that fluoresces orange-red under long-wave UV light. The very first stamp to be issued with Helecon coating applied to the paper was the 11d Rabbit Bandicoot from the 1958-1964 definitive issue. Later, the 5d orange-red Queen Elizabeth II stamp from the 1963-1966 issue was issued with the Helecon incorporated into the ink. By the end of 1965 all stamps issued had Helecon applied to the paper. On this issue the fluorescence of the basic paper varies widely from dead to medium fluorescent, and the strength of the Helecon coating varies also. On this booklet the paper of the panes is dull and the coating is strong, appearing light orange-red under UV.
