The colours were the first thing that attracted me about this, and the enormity of it. This wall is about 100m wide and 6m tall (300x18 ft) and all of it covered in the same style of graffiti (is this graffiti?). I’ve been enjoying this mural ever since this ugly, dilapidated wall got revamped. Luckily, other graffiti artists leave it alone.
Finding a piece of this wall and balancing it and its structures in combination with the lines, arrows and colours took a considerable amount of time.
For those interested: This wall is part of the old, 1869, Koninklijke Nederlandsche Gist- en Spiritusfabriek (Royal Dutch Yeast and Methylated Spirit factory) to be found right here [OpenStreetMap].
EDIT: Spelling is hard. Thanks @elstoc!
