A nice early MHK badge stickpin here, 1st class and dated "1953" on the center diamond. Good condition overall, no major damage or wear. 
 
The MHK was the Hungarian equivalent to the Soviet  "Ready for Labour and Defense" athletic program. The name of the organization is "Munkára, harcra kész" which translates directly to "Ready to work, to fight." MHK existed from 1949 to the mid 1960's
