Hi Classic Banjo Friends,
I got a "new" A notation "Tutor" recently and was able to scan it this weekend to share with the world.

This is one that I have not seen before. It is completely different than the Langey-Fischer Tutor (issued in various formats and titles into the 1950s-- that one, BTW, is one of my favorite "reading" books in A notation, I wish that there had been similar books issued in C notation).
This one, from 1891, includes both fingerstyle and stroke style instruction. I have not had a chance to read through carefully it but I think I see instruction for alternate fingering. 1891 is pretty early for that to show up in a book.
As a nice bonus there is a section of the music that was composed/arranged by Frank B. Converse.
