Like others said, call or email Elmhurst Art Museum this question if you once had a previous exhibition here. This should NOT be asked here!
Google sent your question to me, I am just a guy who VISITED the museum. Why don't you try calling or e-mailing the museum for an answer to this type of question.
This is a Google representation of the museum. You will have better luck trying them through their website or Facebook page.
You'd probably get better mileage contacting them directly through the email listed on their own website than a crowdsourced website that had no affiliation with them. Good luck though,
Thanks! Your answer is awaiting moderation.
