If it weren't for the date on the poster itself, it might be hard to designate exactly when this Elton John concert poster was created.

The rimmed glasses and the psychedelic mirror image definitely take you back to John's '70s heyday, and the greenish backdrop and lightning bolt earring also harken back to an era long past.

Make no mistake, regardless of the calendar year it's hard to think of a better rock concert to attend than one by "Captain Fantastic.'
