Oil-related Postal Stationery:
(items are not all shown to same scale)

A government-printed stamped envelope showing a petroleum
theme on the stamp
as well as the cachet and first-day cancellation.
Imprinted covers are one of the
three main types of postal stationery, along with postal cards and aerogrammes
(air letter sheets).

An example of an imprinted envelope, in this case from the former
Soviet Union that shows a petroleum theme only on the official cachet but
not
on the stamp.
An older example of a Soviet imprinted envelope with a petroleum theme
found only on the envelope's cachet.

Another Soviet imprinted envelope, this one for the 8th World Petroleum
Congress (1971). Although the imprinted stamp does not have a petroleum
theme, the cachet and cancellation do. Note the philatelic addition of an
adhesive
postage stamp that shows the same petroleum-related design as the cancellation.
It was a common practice to issue related stamps and postal stationery for
major events in the Soviet Union.

The imprinted Canadian covers above show normal and revalued (surcharged)
versions of a petroleum stamp that was also released in a slightly modified
formz
as a perforate adhesive postage stamp.

One of the earliest examples of a petroleum-related postal card, this
Polish example
of 1937 shows the Boryslaw oil field on its cachet.
Another early example of a petroleum-related postal card, this
Romanian
card of the late 1930's depicts the Moreni oil field in its cachet

The more recent Romanian postal card of 1965
not only contains a petroleum theme in its cachet
(the projected increase in domestic methane
production), it also features an oil derrick
in the coat-of-arms on the stamp (see
enlargement above).
An example of an aerogramme or air letter sheet with a petroleum theme
shown on
the stamp. You can also see surcharged and overprinted
versions of this item
as well as an error version.
A final, more unusual type of imprinted postal stationery is this 1996
lottery card
from the Peoples' Republic of China. It depicts a refinery on this side and
has
goverment-imprinted postage on the reverse side.
