Pick any piece in the census and draw on it. Thirteen brushes, the colours of the subway lines, a mood for every hour of the city. Sign it, save it, post it. The painting underneath stays MLow's, the marks are yours.
Optional. Your handle goes on the strip under the art, beside the NEW YORKERS and MLOW marks. It stays on this device.
Nothing you draw leaves your device until you save or share it. Your marks do not change the piece, its record or the token.
Every room in the museum carries one sourced line of city history. Flip a card to read it, then mark up the New Yorker who hangs there.
