Hey, Arthur Lee, I would love to psychoanalyze that 1968 picture of John. Or at least know the story behind it. He looks like he's having a good time. It doesn't look like the stress that was Let It Be. 1. Was it really a song he liked and was going well? 2. At first I thought it may have been a Plastic Ono Band recording, but I don't think that happened until 1969. 3. Maybe he was the only Beatle present in the studio. Ringo said the White Album cuts were by John and his band, Paul and his band, etc, the band, of course, being the Beatles. Just not the Beatles as a cohesive, democratic band.
That is a good picture.
BTW I own a New York City tee-shirt like the one John was wearing above. I still have the sleeves attached. I bought it in Manhattan in 2007. At first I saw a tee-shirt with a picture of John wearing the NYC tee; I told my wife I would buy a tee shirt if it was like the one John wore, not one with a picture of him wearing it. On the next rack was the NYC tee.
I remember seeing that Dell comic book picture in 1964, but it was in the middle of a magazine and the background was a red-orange color. I couldn't help noticing how blond John's hair looked even then. The picture also appears to have been reversed, as it was then.
