The masterpiece took community artist Dean The Wizard and 30 helpers three hours to put together at the town's Hub.
This creation formed part of a workshop that links in with the Hub's summer exhibition Let's Play Records which looks at vinyl album art over the years. This exhibition is on until September 5.
Dean, who organised the session to promote the use of recyclable materials, said: "On this occasion I used vinyls and CDs.
One participant, Kitty Butcher, 7, said: "I'm really enjoying myself, this is great fun. I love to do anything arty."
The Hub hosts a number of activities and exhibitions throughout the year. Another exhibition running alongside Let's Play Vinyl is Printshop by artist Belle Benfield.
A Hub spokesman said: "Against a striking backdrop of murals showing industrial wheat processing, Benfield's exhibition includes more than 200 handmade printing stamps that reveal the steps in the process of growing, harvesting, milling, baking and grinding wheat into breadcrumbs.
"This shows a great way to use up old bread has been transformed into a complicated process that we seldom think about as we walk the supermarket aisles."
The exhibition runs until October 3. The Hub is open daily from 10am to 5pm, with free entry.
