I'm not sure what to make of this one. The Academie Duello has previously
offered umbrella self defence classes that referred to Bartitsu, but don't seem
to have resembled it in practice.

In this case, the instructor (David McCormick) may have attended a Bartitsu
seminar I taught in Toronto a number of years ago (I can't recall).

Nice mock-Victorian advertising poster.

Cheers,
