Just as the model name 'Pianola' refers to several self-playing
products of the Aeolian Company throughout its history, from its pushup
player and inner player through the 1950 keytop unit and 1960 64-note
Pianola spinet, so too were 'Duo' and 'Art' applied to Aeolian's 1960's
model line.  Unfortunately they slapped the worthy name on an
unremarkable console style non- reproducer.

I can't place the reference but I have a clear remembrance of a brief
mention somewhere about this second incarnation labeled as 'Duo/Art'
and offered by Aeolian American in the 1960s, when it seemed reasonable
to piano manufacturers that console and spinet players would be just
the ticket for all those newly paneled and acoustic- & linoleum-tiled
basement recreation rooms.

As related in Harvey Roehl's Player Piano Treasury, Hardman, Peck &
Company (a subsidiary of Aeolian American?) introduced their 80-note
Duo spinet (not to be confused with the Duo/Art under discussion) in
1957.  I'm guessing that Aeolian American brought out their own Duo/Art
spinet around the same time or during the following decade.  I believe
I saw one among Lynn Bullock's truly amazing stock on a chance visit to
Piano World during the 1999 AMICA convention in St. Louis.

Note the substitution of a hash mark (/) and lower case characters in
Duo/Art, which differentiates this ordinary player spinet's gold decal
from the decal on our more familiar and beloved reproducing 'DUO-ART',
with all capital letters and a hyphen.

This is borne out on the page of fallboard decals in past and current
catalogues from Durrell Armstrong's Player Piano Company.  Both decals
are shown; the later one with the hash mark and the addition of a
trademark (TM) next to the 't'.  Does anyone know when this symbol
became standard practice on trademark logos?

So this Hawaiian piano is likely not a fake, it's just not all that we
wish it could have been.
