Counter printed stamps are put on the envelopes by the postal clerk directly at the counter which distinguishes them from meters applied by the customers.
In general the postal counter postage labels carry a date. Therefore they are not cancelled by a circular date stamp.
First trials with postage labels date back to the mid of the 1960s. At the parcel post counters at the Port Moresby, Rabaul and at Madang post office so-called cash-register machines were used. These machines did not work as expected. That is why they were put out of service. Hence only very few usages are known.
Since January 1995 renewed efforts were made with regards to counter-printed postage labels. For this purpose the machines produced by the Australian company Hytech were put to use. In English-language trade journals the labels were known as PVI-labels (postal validation imprint) or CPS (counter printed stamps).
Basically the labels may be sorted according to three stamp designs and two different types of paper.
As a specialty a security paper with butterfly print and security thread with hologramme was used. With this paper no prints of the bird of paradise logo are known.
The prints with logo come with five lines of print which have the following meaning:
The first and third line are of specific interest.
The first two digits in the first line identify the place of use. The following 6 digits are the control number. As can be seen from the few examples known only a few hundred prints per machine were produced..
the first two digits correspond to the following places
11 | Boroko | 12 | Pt. Moresby | 21 | Alotau |
28 | Mount Hagen | 41 | Lae | 44 | Goroka |
51 | Madang | 53 | Wewak | 62 | Kimbe |
The machine numbers of line three have four digits. So far numbers between 3397 and 3603 have been recorded:
3397 | 3418 | 3421 | 3447 | 3472 | 3486 | 3491 | 3502 |
3511 | 3517 | 3520 | 3522 | 3550 | 3552 | 3553 | 3561 |
3565 | 3575 | 3583 | 3593 | 3594 | 3595 | 3599 | 3603 |
In the first case time and date are printed. Therefore the place of use is not visible. In the second case there is no date. Instead the line with the place of use is given - 28 Mount Hagen. The printing number must be wrongly set as there are only very few examples known from Mount Hagen.
