This very first Hummel designed Denmark shirt was worn by Morten Olsen in European Championship qualifiers (Denmark was drawn in Group 1 with favorites and eventual Group 1 winners England. Also drawn in Group 1 was Rep. of Ireland, Northern Ireland and Bulgaria) or 1978-80 Nordic Football Championship vs Sweden, Finland or Norway.
The team photos below are from Ireland vs Denmark 1979, the very first game with Hummel as main sponsor for Danish football, and Denmark vs Northern Ireland 1979. Hummel sponsored Denmark from 1979-2004 and again from 2010-2024.
