Beats me, but Loewy and his industrial group DID design:
the coke dispensing machines- the bottle vending machine and the counter-top machine seen in lunch counters
the Studebaker Champion
the 1953 Studebaker Starliner Coupé
the 1963 Studebaker Avanti
the 1941 Lincoln Continental
the DC-3
the Air Force One paint scheme (for John Kennedy- a design scheme still used today).
the PRR S1 Streamliner
the Shell oil logo
the Exxon logo
the US Postal Service logo
Like famous architect Frank Lloyd Wright, Loewy formed a company and became the leader and final approver of work done by his (younger) associates. A lot of his work is on display in the Studebaker Museum in South Bend, IN.
