Thats pretty neat. It caught my eye because I live very close to Manhasset New York. Here's some info I found about that dealer nameplate: "On American cars of that era it was common for dealers to attach cast pot metal nameplates. Nameplates from dealers of that era are hard to find now since most restorers take them off when restoring a car. Recently, because of their rarity and historical significance, people are replating and attaching them on their cars during restoration. This chrome plated dealer nameplate is on Robert Tracz's 1958 Thunderbird Hardtop. It is apparently glued not riveted on. The dealership still exists. It is now called Manhasset Ford Mitsubishi located at 1225 Northern Blvd. in Manhasset."
