What make/model is this mystery car? (any clearer picture?)

Similar angle.

Yeah, if the clearer image you posted is the same vehicle as is displayed this thread's OP, I think you've got it. The body side trim is convincing,
vs the Oldsmobile side-moulding

1956 Oldsmobile 88 Base Sedan 4-Door 5.3L

Okay....I'm fine with a 57 or 58 Pontiac. Definitely not an Olds  or Chevy. I'll settle with the Pontiac for sure. So......hmmmm   what is the reason for the question? What are we looking for here? A car is parked on North Houston facing south and what do we need to know about it??

Just a guess.....  Perhaps someone is suggesting that the car belonged to Jack Ruby who owned a light colored Oldsmobile.
