Most early-20th century Japanese cardboard candy boxes had stick-on doors and windows. In fact, the "windows" were often just doors with the arches trimmed off or some such. Several of the patterns continued well into the cellophane era. The same suppliers who also helped Ted Althof make these reproductions available have helped Pete continue to offer them to collectors, restorers and builders. Plus a few more have been added recently.

This page is a place for discussing these little gems.
