Heller Opus 47 Etudes for Piano published by The John Church Company and it is undated. I believe it to be quite old as there is a small cord woven through the binding keeping the pages intact. Not something you would see on newer pieces of music. Original purchase price was 1.00.
It has 35 pages of music.under the title of Twenty five Studies for the cultivation of rhythm and expression.
Through most of the pages, there is a smudge on the lower right corner or every other page but, it does not block out any of the notes. About 16 of the pages have a tear or two on the bottom margin It looks like the pages are clean except on the title page there is some light writing and on the back free end paper the whole page is a series of musical notations like scales or something. I erased a few words on the title page written in pencil and it comes off quite easily if you wish to do that.
Covers are a light tan and you can see they are lightly soiled. If you are a collector of old music, this would be a nice piece for you to have.
