The production mark 'Walt Disney Productions' was used between 1939-1986, so these toys could have been made any year during that time. They look like rubber, and the paint looks great on them.
Are there any other marks on them, such as a manufacturer?? Do they have squeekers inside?? They are pictured in one of my Disneyana books but if I knew the manufacturer, I could give you a better time frame. There isn't any information under the pictures except that it is on the Figures--Rubber page and says Walt Disney Distributing Co. Lake Beuna Vista, FLa.
That info narrows it down to between 1971-1986.
