Jeep when it gets hot my top comes off shirt

Of note, the trademark name Jeep (calital J and to be used as a name/proper noun) was applied for by Willys in 1943 but it wasn't granted the rights to use the name as an officially trademarked name until 1950. So technically, the 1945 and beyond CJ (civilian jeep) series produced for the general public was an illegal use of the name until 1950 when the trademark was approved.
