Bob Marcks's web site shows this car under the text mentioning Bob working on it following the 1966 Studebakers being styled. It's entirely possible (in fact, likely) that the actual drawing was done prior to 1967 but that's what it is said to depict. Although the changes made to the last production Studes were not excessive and therefore didn't require the longer lead times most styling prototypes go through, the puzzle picture was probably drawn in the mid-1960's, maybe as late as '65. Just a theory.
