BOTTOM THREE ARE OVERSIZED UK SHEETS. Advance sheet music was used by song pluggers to ‘shop’ songs for potential sales to singers or their agents. They are often not (yet) affiliated with any performer so you will not see color covers with singers pictured. When you see larger-sized items at the back of some of my batches, that means it’s often very old (pre-1920) Or a UK COPY. Look close to see if these might be tied to a musical or a movie and esp. look for famous composers. Expect ALL GENRES!!
