This post is meant as an introduction to postal stationery covers from the Soviet Union as they were issued from the first half of the 1950s until the Soviet Union ceased to exist. The covers shown in this post were intended for domestic use, i.e. for destinations within the Soviet Union and other communist countries around the world. Postal stationery covers intended for registered domestic use and for destinations outside the communist block also exist, but are not shown in this post.
First of all a short description on how a Soviet postal stationery can be recognized.
Soviet postal stationeries have an imprinted postage stamp in the upper right corner. The postage stamps can be of either a definitive series or of the commemorative kind. This post will focus on the different definitive series.
In the lower right corner there are lines printed to where the address of the recipient is to be written, below this the address of the sender. Some Soviet postal stationeries were issued plain, i.e. without any images printed to the stationery. This post is about the Soviet postal stationeries that have an artistic image printed on the left side of the cover.
Information on who issued the postal stationery, the date it was commissioned, the price of the stationery and the artist of the image is printed to the backside of the stationery cover.
In the late 1960s a six-digit postal code indexation was printed under the artistic image in the lower left corner of the postal stationery cover. This indexation was to be filled out by the sender, indicating the recipients postal code (ZIP code).
Soviet postal stationeries were printed in large volumes. The ones with artistic images were issued with tens of thousands of different images. Some of them are pure propaganda while others show scenes of the different Soviet republics and their cities, landscapes. For a topical collector there is always an interesting Soviet postal stationery to spice up a collection. The following images are scans taken of Soviet postal stationeries from my collection: "
