Postal vehicles: Function over form
One of my favorite items in my small model collection is a 1:34 scale Grumman Long Life Vehicle (LLV) with sliding side doors, a roll-up rear hatch, and pull-back propulsion. The iconic vehicle has been plying our city streets for nearly 40 years, reliably delivering critical communiques, bills, checks, advertisements, Dear John letters, junk mail, magazines, catalogs, post cards from afar, chain letters, and Amazon packages.
