The Art Dealer's Negotiation

I suggested that I could give
This painting to the museum
In exchange for a means to live:
When they came in at a high sum,
I offered it, sudden, for free,
Except for a mere wage, is all —
I asked if they might employ me.
When refused, I could not recall
My assuredness in dealing,
Could only lunge forward to rise
From a position of kneeling,
And I threatened to aquilise
Lady Sophia Brunel’s nose,
To become an iconoclast;
If it was not sane to propose
What I had, then a rhinoplast
I’d be of this painting’s subject.
Painting, a nation's heritage —
When your value does not reflect
Onto me, I broaden the bridge,
And reduce your value to mine.
