As a member of the Hanseatic League Giese also worked in London where he was portrayed by Hans Holbein the Younger in 1532. After returning to Danzig in 1535 he married Christine Krüger, daughter of a prestigious Danzig citizen.
The Holbein portrait commissioned by Giese, titled "Der Kaufmann Georg Gisze", identifies him by his clothing and instruments as a merchant. The painting also depicts him with carnations, at that time symbolizing his engagement. Also, a plaque depicted over his head identifies him, and states that it shows him in his 34th year, in 1532. He is holding a letter he received from his brother, written in Middle Saxon (“Middle Low German”): “Dem Erszamen/Jorgen gisze to lunden/in engelant mynem/broder to handen” (“To be handed to my brother, the honourable Jorgen gisze at London in England”).

A misaligned set of scales and the placing of a vase of flowers too close to the edge of the table are suggestive of the instability of the world and our place within it.
