Ok, Alfonso. I’ll forgive you.
I did receive my book today, and inside there are some notes about the edition that reads, “the publishers are grateful to Mr. Paul Badura-Skoda for inspecting the original and reviewing Bach’s handwritten entries, the most important of which are listed in the Comments at the end of this volume.”
Supposedly, and I’m sure you already know this, an original edition of the GVs was discovered in 1975 that contains corrections and additions in Bach’s own hand, and this edition is referenced for the Henle edition.
btw – my brain is tired now. I don’t know ‘where in the world’ your picture is from.
