The fourteen year old Prince William of Orange is depicted in full armour, wearing the chain of the Garter and holding a baton in his hand and standing beside a plinth upon rests his helmet and gauntlet. In 1664 Hanneman was paid 500 gulden for two identical portraits (see RCIN 404919) of the Prince of Orange, which were to be sent to England. They were reported to have been considered by the recipients a great success and in return Queen Henrietta Maria resolved to persuade Charles II to sit for a portrait which could be sent in return.

Hanneman was born and probably trained in The Hague, but was in England by 1626 until c.1637 where he was deeply influenced by Van Dyck. After his return to The Hague his associations with the English court made him understandably popular with the House of Orange and later with the exiled Stuarts and their followers.
