One of the Explorer Cars repacked for The Toy House from St Paul, Minnesota. The vehicle still carries its LP trademark.
Next to the logo is a little blurb saying "Advertised in Life" which prompted me to take a look at the Life archives on Google Books in hopes of dating this toy. But the only thing advertised in Life (from the 1950s to early 70s) is the company itself, not its toys. Every other month or so, there's a very small advert showing the logo, a tiny picture of a boy and girl playing and the text "Play tested & sold all over America at popular prices."
