1978 Royal Visit in Guernsey

At the 2009 Stamp Festival in Montpellier, I found this first day postcard in the thematic stock of a Parisian dealer.

The Guernsey Post Office borrowed the famous plaster to its british counterpart to mark with two stamps the visit by the Queen of the Channel Isle, late June 1978. This seven pence with a green background and a twenty pence with a blue one.

Remember, in 1969 already, Arnold Machin's artwork appeared on the first series of the island's postal independence.
