A tribute wall, consisting of 77 messages chosen from over 50,000 tributes left by fans in the book, was unveiled on 3 December on what would have been his 77th birthday.
Sam Watson, chair of Central BID Birmingham, said they were extremely proud to bring the exhibition to the museum with the support of Sharon Osbourne.
“The demand to see the exhibition has been phenomenal and we are very grateful that Sharon and her family have allowed us to extend the exhibition… which will give Ozzy’s fans from the UK and around the world an opportunity to celebrate his extraordinary life and achievements,” he said.
The display also features a selection of Ozzy’s platinum and gold discs, alongside photography and video.
“We are so proud that Birmingham Museum and Art Gallery asked to extend Ozzy Osbourne: Working Class Hero, and that more fans will now have the opportunity to go through the exhibit,” added Sharon Osbourne.
