North Vietnam, Sluice of Lai Lai, May 25th, 1962, Michel Nr. 215; A single stamp in a a 12 xu nominal was issued in perforation 11:0.
Here is a mint block of four:
This stamps were not officially released imperforate however, a small number of imperforate trial proofs have come to market. Rare!
Rare single franking of the 12xu stamp on a letter to East Germany.
Here is a very colorful franking sent to Klewitz in October, 1981. It carries four of the 12 xu sluice stamps and other North Vietnamese stamps for an overall postage of 2.06 Dong. The postage must be accurate as the postal clerk specifically added a printed free frank of 65 xu at the back of the letter. Please note that the 12 xu GANEFO Games value shows a double print of the grey/black color that can be seen as a shadow of the football player. Also the GANEFO Games value are printed on art paper. This can be seen by the fine contours and the slightly darker colors. The GANEFO issue also exists on standard white paper and newsprint.
Here is a letter sent to Klewitz in June of 1962. It carries one of the sluice stamps plus some other North Vietnamese stamps for an overall ranking of 28 xu. That was actually insufficient as the standard letter rate to West Germany was actually 50 xu, however, the sender duped the postal clerk into thinking that the letter was actually addressed to East Germany (RDA stands for East Germany). To that destination the required rate was only 12 xu. So in the eyes of the clerk the letter was actually overfranked.
Very rare letter (ex Klewitz) that features the souvenir sheet among other Vietnamese stamps (including one of the 12 xu sluice stamps). Souvenir sheets on postally used covers are very rare. The editor has only seen one other postally used letter with this souvenir sheet. Overall postage applied of 1.13 Dong. The required postage to West Germany was 1.1 (50 xu base letter rate, 60 xu registration fee).
Registered letter sent from Quan 5 (Ho Chi Minh City) to Klewitz in January of 1982. The letter carries Michel Nr. 1188 in two different color tones plus two Sluice stamps for an overall postage of 8.20 Dong. Green Fulda custom cachet on front.
