Stylized works of art in illustrations

Hi Adobe community,

I’m creating a series of vector illustrations depicting sets of emblematic buildings and major sights (of german cities) in a stylized graphic form. For some additional flavour I would like to include one or two emblematic works of art permanently present in the public space (like the sculpture “Molecule Man” or murals from the “East Side Gallery” in Berlin). Now, to reproduce a work of art in a commercial context you need the premission of the artist (or rights owner) – but is this also true for a stylized interpretation in form of an illustration (i.e. not a photorealistic depiction)?

Cheers, Till.
