Is that it right in front of the (Chevy Nomad??) two toned station wagon?
Wasn't studebaker bought out by Chrysler? Wait, is it also a ragtop?
An old-timer's memories of stuff a half century back, so expect a bit of imprecision. That said, the steam loco is a Norfolk & Western 2-6-6-4 "Class A" - 2-wheel leading truck, 2 articulated 6-whell driver trucks, and a 4-wheel trailing, or firebox, truck - a post-WWII production heavy freight design representative of the pinacle, final evolution designs of the steam era. The jet on the drive-in screen is a '51-'52 vintage North American F-86 Sabre Jet
, looks to me like a like a "C" or "D" variant, though without being able to see the dorsal perspective, I can't be abdsolutely sure of which. I'm gonna say the foreground convertible strikes me as a '53 or '54 GM product, most likely a Buick Custom - might be a Supreme, but I don't think so - though it could be a Pontiac or an Olds, but the left front fender, the hood line, and what can be seen of the dash sorta says "Buick" to me. The station wagon looks to me like a '54 Dodge or De Soto, the 2-tone hardtop to it's right absolutely is a '55 Olds Rocket, and the 2-tone hardtop to the wagon's left looks like a '54 Chevy Bel Aire. The light-colored hardtop up front looks to me to be a '54 Studebaker Starliner. 'Course, I'm an oldster now, I was pretty young then, that was a long time ago, and its a pretty small photo for old eyes.
Oh, and, no, Studebaker wasn't exactly bought by Chrysler - in '54 or so, Studebaker, Hudson-Packard, and Nash-Kelvinator (including the remains of Crosley and Willis-Knight) merged, forming American Motors, which later (late 1980s) merged with Chrysler.
I'm gonna guess the photo was shot not earlier then '55, not later than '57.
