I was visiting a friend and he showed me these neat but odd-looking pirate figures. I took a few quick snapshots on his front porch and posted a pic to the Yahoo Marx Playsets group. A member identified them as "copies of the original Fontanini pirates made by GPS Gavichi of Italy. GPS Gavichi were notorious for copying other companies products, apart from Fontanini they copied Marx and Elastolin." They are about 70mm in size.
The above guy with his pet monkey seems to be everybody's favorite. It's a pain trying to get the detail with the cheesy translucent plastic.
