Booklet 2 sold out quickly, too. Therefore a new booklet was prepared, which should contain stamps of the prevailing inland and Australia standard letter rate of 5 cents. But during the preparation postage for the standard letter was increased from 5 to 7 cents. Therefore the booklet was not issued. The whole printing of the booklet covers, which is said to have been 10 000, was destroyed. Only very few booklet covers survived. To date only four such covers are reported.
A similar booklet was issued on 1 April 1971, which had slight changes in the colour design and, of course, the new value and different stamps.
The next booklet followed only one year later. It contained 5 pairs of 7 cent stamps, Michel number 215-16.
A variety of booklet 4 contains stamps of the Missionary issue of 25 October 1972.
There are three varieties of booklet 5, which may be distinguished by the advertisments on the inside and the reverse of the booklet cover.
As with all PNG booklets, regular printings of stamps in sheet format were used to fill the booklets. For booklet 5 Michel numbers 234-37 were used, which were printed se-tenant in blocks of four. So 25 se-tenant blocks of four make up one sheet of 100 stamps. The strips that were separated out of these sheets had selvedge on the left and the right side. Therefore there are different ways to affix the stamps to the booklet cover.
On the occasion of th INTERPEX Stamp Exhibition in New York 1000 booklets 5a (TAA advertisement) were overprinted with the logo of the exhibition.
To fulfil the demand of collectors all over the world, who could not attend INTERPEX, the overprint was re-printed in Port Moresby with another printing of 1000.
The "New York" print may be distinguished from the "Port Moresby" print. The "Port Moresby" print is aligned a bit more to the left. Therefore the "perforation" of the INTERPEX overprint stretches into the flag of the booklet cover. On the "New York" print, the "perforation" of the INTERPEX overprint just touches the flag of the booklet cover.
A rubber stamp was available at the booth of the PNG Philatelic Bureau at INTERPEX. It is not clear what the purpose was.
This rubber stamp was struck on some regular booklets 5a (approximately 30 pieces) and on very few INTERPEX booklets (approximately 10 pieces).
On the occasion of the BALPEX stamp exhibition in Baltimore in September 1973 booklet MH5a (TAA advertisement) was overprinted with the exhibition logo.
Until now only one of these booklets is known.
Content of the booklets: 10 x MiNr. 647 Bird of Paradise
The booklets were most likely issued on 14 April; 5 000 of each version were produced.
First day of issue cancelled booklets are known, as well as, with dates of 7 April and 15 April.
The stamps in the booklet my be found with marginal inscription "MAY 1992" and "1993". The booklet with the "1993" stamps should be rarer.
In 1998, by accident, some collectors realised that at Port Moresby a provisional stamp booklet was sold. Booklet 7a was filled with additional 5t emergency overprints. So the booklet could be used for standard letters to Australia, which cost 50t at the time, made of a 45t stamp plus the additional 5t emergency overprint. The stamps were added with a staple to the booklet cover.
It can be proved that this booklet was an offiical emergency measure by the testimony of the collectors who discovered the emergency booklets and by postal receipts that were issued when such booklets were purchased at the post office counter.
From this booklet pieces are known that contain the reprint of the 25t stamp of 1996 (Michel number 771) which may be identified by the smaller font used for the value print.
This issue was not confirmed by the Philatelic Bureau in Port Moresby.
The numbers produced are not known.
It is thought that 13 November 1998 was the date of issue. Collectors first noticed the existence of this booklet, when it was offered at the booth of the Philatelic Bureau of PNG during AUSTRALIA 99.
Since then, no further booklets have been recorded.
