Is this PD? It's copyright 1951, i would expect the copyright will've been renewed in the US (though haven't checked), and unless the editor died pretty soon after publication, then it's not PD in canada either.
- Actually, it looks like a reprint of some Russian edition... the title is in both Russian and French (the standard two languages for Muzika apparently, and with Russian on the left side and French on the right) even though BB is an American publisher, and the stage directions are also in French and not English as one might expect for an American publisher.
- And if it is a reprint of a Russian edition then it is in the PD in both US and Canada (Dover and co. reprints Muzika often). --Feldmahler 15:45, 28 January 2007 (EST)
