Off topic here, but I wonder if Little Guitar has a larger size pic of that avatar pic. I'd like to use it as a visual reference for an upcoming project.
It looks like a contemporary recreation of a cool Bowie shot though. The lighting and film stock look too contemporary to be from the 70s. If it's photoshopped, then someone did a heck of a job.
LOL, it's a classic Mick Rock photograph from '72 or '73. It may feel like ancient history, I guess. He was among the most famous Ziggy-era photographers and his pics of Bowie as Ziggy tend to be very colorful... he's really a wonderful photographer.
OK, I promise to return to topic after this...
