Hello, recently purchased this lithograph signed by the Dio era lineup of Black Sabbath, being Ronnie James Dio, Tony Iommo, Geezer Butler and Vinny Appice. Whilst I am fairly confident in these myself I thought it wouldn't hurt to check with anyone more knowledgeable - worth noting that the era of this will be around 2007-2010 and the litho itself I believe to have been either sold on or part of a VIP package for the Heaven and Hell band's tours.
