Well over 20 years ago, Eric Kriss did a couple of books of transcriptions of blues piano--Six Blues Roots Pianists and Barrelhouse and Boogie Piano. I don't know if those are still in print.
Second one is, first one isn't I believe.
Correct, but right up my alley. The Kriss has lengthy "musical notations" for each of the titles under discussion, intended for folk to play. He also includes numerous short excercises. For some bizarre reason when published (1972, MJT3) it came my way for review! Here's the contents list :
