Ann of Byerly's. Byerly's is a Columbus aquarium shop. Old and well established with dozens of large tanks filled with fresh and salt water fish. There were many bright young people who worked there and they all wore forest green tee shirts with the company logo on them.
Ann was a particularly lively young lady who was looking forward to marrying a month or so after I took my impressions for this painting.
Here is a detail which renders the color somewhat better.
