Alas, we will never be able to assess the legendary "O-So-Eesi
Piano-Player" . In P.G. Wodehouse's short story, "Ukridge's Accident
Syndicate", first published in 1923, a minor character is "Victor
Beamish, the artist, the man who drew that picture of the O-So-Eesi
Piano-Player in the advertisement pages of the Piccadilly Magazine".
I wonder if Wodehouse was "inspired" by the Gulbransen baby?

If I ever get my 1928 Gulbransen Triano upright restored I hope it
lives up to Gulbransen's reputation.  It is an odd little critter --
a pedal/electric Recordo with no fold-down treadles but what appear
to be three piano pedals.  The middle one is sustain but the outer
two are pumpers.  To play a standard 88-note roll you use the electric
motor and pump to power the roll drive but you pump the stack with
these little pedals.

I'd be interested to know if there are many of these pianos around.
There are a few in Australia and mine turned up here in New Zealand.
