Art Magic And Its Author(s)

A vexed question: who wrote Art Magic and under what circumstances? AE Waite and Olcott, among others, were willing to say in more or less public forums that (a) significant borrowing, verging on plagiarism, was to be found in Art Magic, and (b) EHB almost certainly was the author. But then each of them had an axe or two of their own to grind.

In that context, then, this interesting snippet, from The Manufacturer and Builder, a building trades magazine, of November, 1876 (pp. 260-21).

Smacks of Olcott's diary entries, to me. Note to self: who edited this magazine in 1876?
