The scan above shows the only cover I have observed for this issue bearing the words "Premier Jour". The blue cancellation on the top left is dated 30.06.1993 whilst the circular date stamp on the top right is dated 01.07.92. However, this cover also bears the fake overprint No. T4F (USSR 1k green definitive from 1976) and therefore the cover itself must be considered to be a fake.

The scan above shows an old USSR postal stationery card bearing all 4 of the red overprint stamps. There is a rare commemorative hand stamp on the left which indicates the second anniversary of independence. The special cancellation in the centre and the circular date stamp at the top right are both dated correctly as 02.09.92. This is a commemorative cover only.

The scan above shows an old USSR postal stationery card bearing all 4 of the black overprint stamps. The special cancellation in the centre and the circular date stamp at the top right are both dated 02.09.92, the second anniversary of independence. This is a commemorative cover only.

The two scans above show all 8 overprint stamps with special cancellations and circular date stamps for 02.10.92. These covers were prepared to commemorate the 200th anniversary of the City of Tiraspol. These are commemorative covers only.
