Thanks scchua,
Pic 5 is a HALO parachute descent.
Is 2 across inthe raw or all fresco ?
Thanks to Armonie and scchua.
Pic 2 includes Chuck Connors who played The Rifleman on TV.
Cheers…
Hi Muffyword, grimalkin, grandpuzzler: You’re right about High Altitude Low Opening parachute jump, and Chuck Connors, the RIFLEMAN. Pic1 is an MRI scanner, for which STIR is an acronym for a technique to get a certain type of contrast in the images. Pic3 is Jake LaMotta, boxer aka The RAGING Bull. Pic4 is a map showing, in the upper half, Vanuatu, whose name when it was a colony was New HEBRIDES. Pic6 is a wine cellar, possibly in Tuscany, where the FRESCObaldi family is a famous wine producer.
I thought it was either Jake LaMotta (and wife Vicki) or Carmen Basilio having gone fifteen
rounds with Sugar Ray Robinson. Unfortunately, I didn’t recall the movie title so didn’t
pull the trigger. Next time…
