Hello, everyone!

I'm new, here! My name's Davide, from Italy; and I'm interested (or rather
obsessed) in everything that's raggy, jazzy, bluesy or simply syncopated. Oh... Not mentioning I'm also a great fan and connoisseur of avant-garde music. In all honesty, I still can't believe I found such a gold mine in this little corner of the Internet.
I propose you a challenge. Could you help me in obtaining Leopold Mittmann's (avant-garde) Jazz works, please? As far as I know, he wrote at least three Jazz works:
Jazz-Etüde (19??),
Jazz-Konzert-Suite (1929) and
Jazz-Babies (1946). In all honesty, I'm not very sure if any copy of his
Jazz-Etüde has survived to this day, actually.
In return, I'll be extremely happy to share with you all one of the rarest (and interesting) German Jazz Novelties folios ever

I'm speaking about the
unfindable Gerhard Mohr's
Stars folio (1929). And, in addition to this, I will also share with you
Léo Laurent's Original Swing Piano Conceptions Voll. 1 & 2 (1930s).
Thank you for your attention!
