From an edition of one.60 vintage prints as one set from GINZA NIKON SALON exhibition, Tokyo in 1988.
Signed, titled, printing date, edition (1/1) in pencil on the reverse / mint condition. Aside from numbered edition of 25 and 5 artist's proofs.
After following the crowd for a while, I'd then go 180 degrees in the exact opposite direction. It always worked for me, but then again, I'm very lucky.
