Here is the mint stamp
and here the postal used stamp
This stamp was not officially released imperforate, however a small number of imperforate trial proofs have come to market. Here is a pair of them.
A very small number of Enpreuve de Luxe imperforate sheetlets, also called “Minister Blocks” were produced on light carton paper which had imperforate samples of the stamps attached and were handed out or sent to very important people of other countries. These early sheetlets are very rare and seldom come to market as most of them ended up in the archives of foreign postal administrations. They are not comparable to Enpreuve de Luxe issued later primarily for the benefit of collectors. Note the dry seal of the Vietnamese postal administration. It is covered by a glued on glassine with a message from the Postal and Telecommunication Ministry.
