We had one similar to this except with a red stripe. Not the car though, ours would have been a '54 or '55 Chevy or Olds.
The camper was a 13' Comet that Mom and Dad purchased new in 1956:
There were 5 of us kids, Mom and Dad on a 2 week trip each summer... can you imagine? Sheesh.
On my first trip I was 6 months old and slept between my parents feet on the bed, sis slept on the table made into a bed,
one bro slept on the floor and my 2 older bros slept in a pup tent.
