ALL THESE RARITIES... AND MUCH MORE!
In the 1960's and 70's, a lot of young people came to music, and especially to guitar playing, through Bob Dylan's songs. In the early 60's song sheets were very cheap: they allowed you to get the lyrics and the chords, and become Bob Dylan for a while in your bedroom.
When compilation songbooks appeared, they quickly had a great commercial success, gathering in one book the well-known anthems, and even some never heard songs...
Soon every Bob Dylan album released was followed by the publication of its own songbook; all of them are highly collectible.
