I think this is from Halloween 1976. I would have been only 9, and so still at an age where making a cardboard Liberty Bell costume, and painting it red, white, and blue, would have seemed like a good idea.
I finally finished uploading all the slides I had scanned in by ScanCafe. There are a bunch of good ones in there. Some very nice photos from Japan, though some seem to have picked up some mold or something that couldn’t be removed by their digital ICE.
