These costumes were listed only in the 1962 Collegeville Costumes catalog.   Recently, a barn filled with old Halloween and novelty store stock was sold as part of an estate stale, and a number of Kukla and Ollie masks were part of the find.  No one knows why the stock was there, but as a result these masks can be found for a steal.  Kukla is nice, and Ollie's day-glo colors are truly bizarre.  The complete costumes are hard to find, and apparently came in different versions.
