Most of Baaah! art is based on Nigel Evans original photographs which have been digitally enhanced
Brecon artists Karin Mear and Nigel Evans, jointly known as Baaah!, are showing their work at the Brecknock Museum and Art Gallery.
On display will be large pop-art-style images of sheep and other domestic animals against kitsch and cheerful backgrounds.
It pays homage to farm animals which can be seen on and around the Brecon Beacons.
The exhibition runs until Sunday, 8 August.
Baaah! has been an on-going project for the two artists for the past six years since returning to live in Wales.
Both Karin and Nigel were previously freelance graphic artists working for large companies in London.
"We decided to move from London and live near Brecon about eight years ago," said Nigel, who is originally from Aberdare.
"At the time we were doing a lot of pop art so when we moved to Mid Wales the project evolved as a response to the role of domestic and farm animals in local life."
The portraits are based on old school photographs from the 1960s
Pop art uses the imagery of popular culture such as advertising and consumer goods such as Campbell's Soup Cans labels created by Andy Warhol.
The portraits in this exhibition are based on old school photographs from the 1950s and 1960s, where children were often photographed in front of patterned wallpaper.
Fabric designs such as a shirt with a sheep pattern on it are also on show.
"Our objective is to highlight the importance and familiarity of these animals in everyday life in the Brecon Beacons," said Nigel.
The exhibition will be up over the weekend of the Brecon Fringe Festival between Friday, 6 August and Sunday, 8 August, and there will be live music in the exhibition gallery during the festival weekend.
Abigail Kenvyn, assistant curator at Brecknock Museum and Art Gallery, said: "This exhibition is a fantastic example of the strong, persuasive influence Brecon and its culture can have on artists."
