The four string instruments on Spain stamps 2011

The mandolin is a musical instrument with four double strings and a soundboard which can be concave or flat. It is of Italian origin and has been used by many great classical and modern composers both in traditional music as well as in other music styles. Among its variations is the Italian mandolin, folk and bluegrass.


Early mandolins had six double courses of gut strings, tuned similarly to lutes, and plucked with the fingertips. Modern mandolins—which originated in Naples, Italy in the late 18th century—commonly have four double courses (four pairs) of metal strings, which are plucked with a plectrum.Many variants of the mandolin have existed.
A mandolin may have f-holes, or a single round or oval sound hole. A round or oval sound hole may be bordered with decorative rosettes or purfling, but usually doesn't feature an intricately carved grille like a Baroque era mandolin.

Agriculture in Liechtenstein

Agriculture was the key implement in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that nurtured the development of civilization.
The graphic artist Silvia Ruppen, who was commissioned to design the “Agriculture” stamps, has performed her allotted task by depicting in sequence the specified topics “Space”, “Environment”, “Technology” and “Animals”. The stamps are issued on March 2010 and comprised of 4 single stamps.
The artist has assigned each stamp to a season as indicated by the colours used so as to be able to portray the farmer’s year in colour too: for example the first stamp is coloured in cool greens, blues and greys, representing the winter season. In the second stamp the bright, warm green shades of spring predominate. The rich gold and red tones of the third stamp refer to the sun and the ripe crops of summer. The fourth stamp with its russet autumnal colours concludes the annual cycle. The graphic artist has realised her designs in coloured pencil.

The viewer approaches the group of topics from a distance. To begin with his attention is on “Space” (face value CHF 0.85), i.e. the meeting between living, relaxation and agricultural space. The slogan here is “Far-sighted spatial planning preserves living space for all”.

Renewable Energy on the Liechtenstein’s stamp.

Renewable energy is derived from natural processes that are replenished constantly. In its various forms, it derives directly from the sun, or from heat generated deep within the earth. Included in the definition is electricity and heat generated from solar, wind, ocean, hydropower, biomass, geothermal resources, and biofuels and hydrogen derived from renewable resources.
During the five-years from the end of 2004 through 2009, worldwide renewable energy capacity grew at rates of 10–60 percent annually for many technologies. For wind power and many other renewable technologies, growth accelerated in 2009 relative to the previous four years.
The “Renewable Energy” series of stamps is devoted specifically by Liechtenstein Post to these energy sources, which are characterized by being self-renewing and thus sustainably available resources.
The first part of this series highlights “Hydropower” (face value CHF 1.00), “Wood” (face value CHF 1.40) and “Near-Surface Geothermal Energy” (face value CHF 2.80) as such renewable energy sources.

“Hydro-power” (face value CHF 1.00).
Energy in water can be harnessed and used.Many forms of water energy such as Hydroelectric energy,Micro hydro systems,Run-of-the-river hydroelectricity systems and Ocean energy describes all the technologies to harness energy from the ocean and the sea.
