A drawn picture of Santa with a speech bubble saying "Merry Christmas!". He is holding a present wrapped in gift-paper decorated with snowmen, and with a tag with the Isaac logo, in the shape of an abstract, hexagonal apple. In the background, there is a vehicle moving on a slope and a dripping burette.
