Color Trials; prior to authorizing the final printing run for stamps the Vietnamese Postal Authority requested a few sheets of color sheets on one particular value of a set in order to decide which final color combination would be best suited for each stamp within the set. The color sheets had the size of a standard sheet but contained alternating color options on the designated nominal value. While these sheets were only intended for internal postal use some of them came to market. Virtually all of these complete sheets were cut apart. So one mostly finds single color proofs or small strips of them. While they are actually very rare one can still obtain them for under $10 a piece (with some exceptions) as not many collectors appear to have an interest in them so far. Here are various color trials for the 3D value.
Very rare single franking of the 50c value on printed matter mailing by the Carmelites of Hue to a donor in France from 1961. Most printed matter mailings were simply thrown out and hence are now very hard to find.
Rare multiple franking of the 50c value (13) paying an overall postage of 6.50D on an international air mail letter sent from Saigon to Portugal in February of 1961.
Rare multiple franking of the 1D value (2) paying 2D on a domestic letter (full contents preserved) sent from from Cai Lay to Thi Nghe from December 1961. Saigon machine arrival cancel on the reverse.
