Help deciphering this Japanese artist's signature


I know this is a long shot but I came across this Japanese artist's signature
and I was wondering if anyone could help.

Unfortunately I do not know the full name of the artist. The rightmost
character is clearly 敏. The roman letter part seems to spell "Bando" or "I.
Zando" or perhaps "I.Z. ando". The middle character is the most interesting to
me. It's clear that the leftmost part of the character is the radical 玄, but I
could not find any kanji with 玄 in this position. The middle part looks like a
mirrored 了 and the rightmost part looks like some sort of dotted ま.

If anyone has any clues for understanding this signature, they would be
greatly appreciated!




Possibly 敏雄? There is a [Wikipeadia article (linked to French
one)](https://fr.wikipedia.org/wiki/Toshio_Bando).
