Greytown-based artist Steffen Kreft is displaying 383 individually-designed postcard reproductions at Aratoi as part of the Kokomai Creative Festival.
The postcards, created by Mr Kreft in his home country of Germany, were mailed to friends throughout the world, with Kreft making and mailing one postcard each day for more than a year.
He said that the One Postcard a Day project is his favourite work of all he had undertaken.
"It was just so wonderful to do," he said.
"It was a threefold concept of the postcards being a diary, a way to connect with friends, and it was a piece of free art that I do every day.
