Often the back cover of sheet music shows publicity or part of the publisher’s music catalogue. It is seldom blank. But it is much rarer that the back cover (verso) is illustrated to form a whole with the front. Something that today is common on e.g. book wrappers. In our collection of sheet music we found only six of such ‘full covers’. These were probably luxury editions as we can imagine the cost of making such large lithographic plates. We happily share these ‘specials’ with you.
