Pierre Probst: The French Shorts, 1960-1979

I don't know much about these, but they have a distinct style difference than their 1980s/90s counterparts. They tend to pull in a little more money on Ebay, also, but well below the English versions. One can usually find these for under $50, sometimes as low as $10. These are the ones I've seen up for auction. Many of these have British or American counterparts that have been published.

Les Vacances de Caroline, 1962
    This appears to be the same as the "Caroline at Camp" story in the American Treasury.
La Maison de Caroline
    This appears to be the same as the "Spring Cleaning" story in the American Treasury.
