One of the many stamps out there commemorating sporting achievements, or sporting events. This one is quite unusual, it is in honour of the 7th annual staging of the Tour of Columbia (Vuelta a colombia). Issued in 1957, it is a set of two air mail stamps, printed in Austria. This is the 2c in brown, there is also a 5c in blue. A very fine etching of the rider and bike on an offset diamond shape.
