The 2017 Royal Mail Racehorse Legends issue consists of eight stamps, each featuring a horse that has won one or more of the UK's most prestigious races and therefore left their mark in racing history. The horses featured are Red Rum, Arkle, Desert Orchid, Kauto Star, Estimate, Frankel, Brigadier Gerard and Shergar.
The eight stamps from this issue feature on our BLCS 5000 cover, and bear a pictorial Cheltenham handstamp, location of the famous racecourse which hosts the Gold Cup race that runs during the March Festival.
