I got one of these a few years ago, a library DISCARD - can you believe it?Originally c1967, Oak Publications. BTW, it's Hard HITTING (not HIT), for those who are looking for it.
These aren't happy songs, but important, nontheless. Nice pictures. Song notes by Woody, transcriptions by Seeger. Forward by John Steinbeck. It's from a 1941 publishing project that was scuttled because of WWII, reassembled in 1967.
It would be at home in any collection.
