Royal Portrait Stamps

On 30 May Royal Mail will issue a set of stamps featuring Her Majesty the Queen: Six Decades of Royal Portraits (CLICK). Four of the six portraits - by Terence Cuneo (1953), Pietro Annigoni (1955), Richard Stone (1992) and Andrew Festing (1999) are excellent, but two are dreadful. Sergei Pavlenko seems to have confused Dame Helen Mirren for the real Queen (2000). The portrait shown (2013) was commissioned by Royal Mail from an anonymous artist and is one of the worst I've ever seen.
