Did you know that the US President Martin Van Buren coined the saying 'O.K?' Design firm 'Acrylicize' decided to commemorate this proud historical moment for UK's The Office Group's new building opening -- where Martin Van Buren actually use to live -- with a cheeky presidential portrait of the eighth US president.

To complement the iconic Victorian structure of 'he Office Group's new location, Acrylicize designed a traditional oil-painting of Martin Van Buren but modernized the presidential portrait by having Van Buren doing the quintessential O.K figure gesture. A beautiful period painting that is detailed, modern and humorous, this presidential portrait beautifully highlights old school art customs while simultaneously nodding at Martin Van Buren's historical O.K pop culture reference. I think Martin Van Buren takes the cake with the coolest presidential portrait out there, what do you think?
