This theme was only sold in European markets. It was the result of a 3-year license agreement with The Walt Disney Company Ltd. to produce wooden railway and preschool toys around the “Playhouse Disney” programming.
Do to the gap in catalogs in the year 2009, it’s not clear if the Disney Theme was released in 2009 or 2010. Regardless of the time, it was a short-lived theme: its last appearance was in 2011.
It didn’t appear in the Wooden Railway catalogs, probably because the relaunch of the Wooden Railway line in 2010 came with an emphasis on building realistic worlds. You could only find the Disney products listed in the general catalog and printed on the catalog inserts.
