"More in things than in people" is the first solo exhibition by
O'Sullivan-Tyrrell at the Green Door Gallery. With this series of small format oil paintings, most on wooden panel, the artist contemplates the objects we choose to surround ourselves with; how "their dogged and contrary existence" speak to our identities and how we curate, and even fabricate, our memories.. ​
