The exhibition features 16 Gromit sculpture designs, which were created as part of The Greatest Dog Show On Earth showcase in Hong Kong in July 2014.
The creations are to make their UK debut next Monday (1 February), when the 10-week exhibition is unveiled at The Grand Appeal’s store at The Mall, Cribbs Causeway.
The collection incudes scuplutures by Aardman designers Gavin Strange and Ashley Boddy, who will officially open the exhibiton.
Gromit Unleashed is free to enter, however visitors are encouraged to donate £2 upon entry, with proceeds donated to The Grand Appeal.
The charity hosted the inaugural Gromit Unleashed trail in Bristol in 2013, an initiative that saw 80 Gromit sculptures raise £2.3m for the Bristol Children’s Hospital.
Last year Shaun the Sheep's art trail across London and Bristol culminated with The Great Sheep Round-Up exhibition in London's Covent Garden, where funds raised were similarly donated to charity.
