How many letters have you got to play with? A song lyric perhaps?

lazy

artists

(Eines words not mine! )

happenstance is 12 letters so would make a nice 4x3.

red green blue (in whatever colours you like)

baywatch

To be topical why not ask for:

Provenance

Fraudulent

Don't get me wrong with what I am about to say because I love Ben's stuff and own two of his prints but how about:

"This is not art"

colossal - it always sounded cool

Screeched - longest one syllable word in the English language... second thoughts if you ever watched 'saved by the bell' when you were a kid it may put you off...

Calenture

"A febrile delirium, said to be peculiar to sailors, wherein they imagine the sea to be green fields and will throw themselves into it if not restrained. [Hooper1829]

Fever. The term was used by the old Spanish navigators to denote any form of fever with delirium observed in the tropics, and from them Sauvages adopted it as the name of a special disease (which has been described as peculiar to mariners and characterized by a particular form of delirium in which the patient, unless prevented, will jump into the sea, thinking that he is walking into green fields); but its use in the sense has been discarded. [Applton1904].

A name formerly given to various fevers occurring in tropics; esp. to a form of furious delirium accompanied by fever, among sailors, which sometimes led the affected person to imagine the sea to be a green field, and to throw himself into it. [Webster1913]"

You could also just go for "Commissioned"
