"As we spoke to the artist, Marcus Jansen, I told him I believed he was the originator of a new movement which I called “Urban Expressionism” and that I believed that there will be many followers in this new style. But there will only be one Marcus Jansen.

- Jerome A. Donson (Art Historian and Director of the American Vanguard Exhibitions Europe 1961, MOMA, New York)

"The American myth needs to be reexamined in the twenty-first century, even rewritten. One of the most important contributions in this regard is being produced by the American Marcus Jansen. With Caribbean and German roots, he is a painter through and through, a painting diagnostician with a gaze as comprehensive as it is incisive.
