Both the medal and suspension device are in gilded brass. The medallion measures 32.0 mm in height incl. eyelet, 30.0 mm wide; the suspension is approx. 26 mm tall x 23.5 mm wide; overall height of the medal including suspension is approx. 58 mm. The medal is very well made and quite massive for its size. The obverse shows the building housing the headquarters of the SEV (Komecon) organization - at the time, one of Moscow's only skyscrapers - and has a Russian- language inscription "Council for Mutual Economic Assistance". The reverse of the medallion shows an inscription "For Participation in Building Objects of Socialist Integration". There is a raised logo of the Leningrad Mint on the reverse of the suspension device.

Very fine to excellent condition. There is mild tarnish that adds character while the gold finish remains bright and free of blemishes or significant wear. The ribbon shows age but is sound and attractive.

The medal was awarded to Soviet and Eastern European workers building major infrastructure projects for the Eastern Bloc countries of the "СЭВ" (aka Comecon in English usage or Council for Mutual Economic Assistance, a Soviet-dominated economic union of the Communist countries). The specific program, the so-called "Complex Socialist Economic Integration", was adopted by the Comecon in 1971. Beside their economic value, the joint projects served as an instrument of Soviet political influence (and in many cases, are used to this effect by Russia even now.) Like other similar awards, the medal - or "honorary badge" according to the official Soviet hierarchy of awards - was established by the Executive Committee of Comecon.
