Another copy of this
print is shown on line at the Boston Museum of Fine Arts
web site. It is from the William Sturgis Bigelow Collection -
accession number 11.39688
Although this is
posted as a Kuniyoshi at the museum's site it is only done so because it
glued to the back of the featured item with
the accession number
There is another copy
of this print in the collection of the
Museum für angewandte
Kunst in Vienna.
And still another copy
in the Tokyo Metropolitan Library where there are two other related prints.
While they may not
form a triptych they are, at least, from the same series.
