This listing is for a booklet by Beryl Rubinstein "Outline of Piano Pedagogy".  This is the fourth printing and it was printed in 1947 (MCMXLVII).  70 pages and published by Carl Fischer Inc.

Booklet is showing cover wear but flips through nicely with clean pages.  Little thing with with one of staples and the cover but it holds together nice (see video)..See pics and the video shows a lot.
