UPDATE: I found this article that highlights the inspiration behind the book Creeper’s Jeep. It was published in the Bridgeport Post on August 22, 1948:
The book is still available on eBay, but they aren’t cheap: https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2380057.m570.l1313&_nkw=%22creeper%27s+jeep%22&_sacat=0
======================
Originally published May 18, 2016: This book was listed on eBay.
“This listing is for a vintage book entitled “Creeper’s Jeep” by Hardie Gramatky. It is a cute story about a guy who owns this jeep that wants to share it with his family. They do not take to the idea at first but after a few incidents decide to give it a try. Great illustrations: see pictures. Former library copy with some of the usual markings.”
From an earlier eBay posting that sold in 2013:
I fondly remember reading this book in second grade at the Franklin School in Lexington, MA.
This was around 1957 and sice the I have owned 3 Jeeps! A 1954 CJ-3B, a 1973 CJ-5A,& a 2005 Jeep Liberty. I had the most fun with the 1954 CJ-3B which remided me of Creeper’s Jeep! Andy
