Also, the version that this person is selling is from the 2015 Studio Collection box set. In making all of the albums colored vinyl, they decided to keep with the Side White and Side Black concept by putting each side on it's appropriately colored vinyl with the Queen Crest laser etched onto the other side. If you buy the album on it's own, it still is the standard single album.
in other words they are not spreading the album out over 4 sides. the album is actually pressed on 2 sides. 33.3 not 45.
collector edition, half speed mastered. one black vinyl, one white vinyl.
if you buy the (much cheaper) standard edition.... same pressing, half speed mastered, 2 sides on 1 vinyl. black.
