I felt ‘yes’ was the only answer.

I received an email from Rita and the Plein Air Team on Monday 27 August which read:
Dear Ruth,
On behalf of the Parliament Plein Air Painting Prize 2018 selection panel, we are pleased to inform you that your artwork has been selected for the further stage of the judging process. This process is to ensure and confirm the artwork is of a high standard as represented by the digital image we received. Successful finalists will be notified on Friday 14 September of their participation in the exhibition, and the winners will be announced in October while the exhibition is on show.
I was chuffed! I didn’t read much more. I really should have read the rest that explained:
Additionally, I would like to consider your artwork as the identity of the Plein Air Prize for 2018 for print, outdoor and digital promotion. I’m sure you understand that this does not reflect the winner which is announced in October and selected the Final Judge. Your image however would have high visibility should you approve our request.
Your response with permission would be greatly appreciated.
Please forward your selected Artwork: “Liverpool Plains from the Hill Behind Nick’s Place

And I had ignored the request!!
Rita did not give up on me or put off by my tardiness. I am indeed grateful as Rita rang me on Wednesday to ask if I had read the email they had sent me? Rita explained what they were asking and after some chat and explanation I gave approval for the image to be used. It was so unexpected. Huge thanks to the Plein Air Prize team at Parliament of NSW for considering me. I am honoured
