In case you didn't see it in yesterday's NYTimes Magazine -- Paul McCartney and Astrid Kircherr on the beach at Tenerife, late August 1963.
This was the Beatles first real jet-set vacation, and the last before the onset of all-out Beatlemania world wide. Kircherr says the picture was probably taken by George Harrison, with her camera. Ringo Starr was also along for the trip; John Lennon was on his own separate holiday in Barcelona, where he famously did or did not have sex with manager Brian Epstein.
In any case, a remarkable photo; on Sept. 24 and 25, the actual print -- along with 600 more pieces from Kircherr's Beatles photo archives (negatives included) will be auctioned off at Guernsey's in Manhattan.
