This is a high-quality, US-made gasket for the famous Vespa "Mickey Mouse" rear light. The so-called "Mickey Mouse" taillight is most associated with the '66-on Sears "Blue Badge" largeframe and smallframe Vespa models as well as on a short-run of (Vescony - East-Coast distributed) SS180 Super Sports. There were also a handful of very late Sears Allstate VNB models equipped with this light as well as a few of the very last batch of US-import VBB2T models in late-'65. Ref: MM_TLGSK
