It looks like what Cadillac was using in that timeframe (on into the mid-60s for that matter) but not sure if Oldsmobile was using it or not. Cadillac, Buick and Oldsmobile windshields, doglegs and upper doors are very similar in 1957 and 1958 so it could well be a factory or dealer option.
Someone with 1957 sales literature and option list will have to say for sure. Check with Clay Tober, 57 Chapter OCA Advisor 4 four 0- five two 6- five 159.
