"The commemorative stamp series in tw o denominations were designed by graphic artist Ágnes Berta and printed b y the State Printing Compan y.

The stamp s eries will be published on 22 June 2012, the official day that Hungarian Ol ympic participants take their oath, a nd a few days later, on 25 June, their ceremonial launch w ill take place in the Hungarian House of Sport. According to research, the first Olympic Games were held in 776 BC, following which they were usually organised every four years. The popularity of the games continually increased and reached its zenith in the 5th and 6th centuries BC. The revival of the Olympic Games in modern times is linked to the name of Pierre de Coubertin, who sought to renew the celebration of sport and to facilitate this summoned together a conference lasting from 16 to 23 June 1894 under the auspices of the French Union of Athletic Sports Societies. He conveyed his aspirations at the congress and the participants made the decision to renew the Olympic Games, set the first venue and established the International Olympic Committee. The international 30th Summer Olympic Games will take place in London between 27 July and 12 August 2012. Through this London will become the first city to organise the modern summer Olympics three times since it has already hosted on two other occasions, in 1908 and in 1948. The IOC selected London to organise the summer Olympic Games during its 117th session held on 6 July 2005 in Singapore. The city’s tender beat Moscow, New York, Madrid and Paris in a four-round vote. The Olympic flag was hoisted before London City Hall on 26 September 2008. The Olympics will be organised in a total of 39 branches in 26 sports. It is anticipated that 204 nationalities will be represented by their sports people with over 150 contestants representing Hungary."
