The Royal Mail asked budding young artists to come up with designs on a pandemic theme.
The drawings feature bus and delivery drivers, NHS workers, vaccine scientists and food bank, volunteers.
The winners, from across the UK, were congratulated by the Prince of Wales at a special reception.
The competition, launched last spring, attracted an “unprecedented… and a world record-breaking 606,049 entries”, the Royal Mail said.
Judges, including retired teachers, selected 120 regional finalists.
A panel, including the prime minister and former BBC Playschool and Playaway presenter Baroness Floella Benjamin, then picked 24 regional winners.
The final eight winning designs were personally selected by Prince Charles, with the finished stamps approved by the Queen.
