Introduction
In this article, we will show a number of covers with date stamps or slogans allowing to frank stamps and not described in the previous articles. We will also show a number of anomalies arising out of the operation of franking machines. Note that this article owes a great deal to the two publications [18] and [19] by Yves NOUAZÉ.
Slogans and date stamps
We will present the slogans of the various machines used during the validity period of the stamp 0,50F Marianne de Béquet. We will also show some date stamps not described previously.
Use of coloured ink
Anomalies
Here are some anomalies found about slogans.
Complementary postages
We will show postages by means of postage meter impression ( E.M.A.) or sticker counter.
Special postmarks
Some slogans are rather service marks of certain units of Post offices. Some of them can however be found on surface mail.
