Economy of Liechtenstein
The economy of Liechtenstein is based roughly equally on services (especially financial services) and industry, with a small but significant agricultural sector. The country participates in a customs union with Switzerland and uses the Swiss franc as its national currency. It imports more than 85% of its energy requirements. Liechtenstein has been a member of the European Free Trade Association (EFTA) since 1991 (previously its interests had been represented by Switzerland). It also has been a member of the European Economic Area (EEA) since May 1995 and participates in the Schengen Agreement for passport-free intra-European travel.
Postage stamps and postal history of Switzerland
All of the preceding issues were declared invalid on 1 October 1854, and replaced with the seated allegorical figure "Helvetia", the first of several issues known as "seated Helvetias". The figure was embossed but only the outline was colored, making it rather hard to pick out. This was the first issue to deal with the multiple languages of Switzerland; in addition to the word "FRANCO" at the top, the other three sides listed the denomination in rappen, centimes, and (Italian) centesimi.
