I have an unsigned copy. I bought it online new just a few years ago. It's just a grab bag of previous sessions. IIRC The Royal Garden is from a mgm 10' lp, When The Saints Go Marching In. Quite a few tracks are from Kapp MS 7520 The Battle Of the Dixieland bands. This has Doc Cheatham, Red Richards, Vic Dickenson, etc. There's the session with Miff and Pee Wee that was on Jazztone. Susie is from Bud Freeman's Summa Cum Luade Bix album. Apologies for being vague - I haven't a chance to listen all the way through now, but I think that covers much of it.
Edit to add: By the time I posted I saw Jazztrain's post. I think what he says plus the Kapp lp and the MGM lp pretty much cover things.
