This is a autograph
that JOHN wrote on the back side of T-shirt
in 75. This signature is written with a black
magic-marker. By the story from the person who
obtained this autograph, when he visited peddling
to Karuizawa in 1975(Perhaps it was in 79 ,his
memory might be wrong), he found John by chance,and
asked autograph on his T-shirt which he wore.
This is one of very few autographs that John
left in Japan. The condition is not bad though
the color of T-shirt has changed a little in
green in year of passing.
