Well this thread is joyfully spinning out of control! Must be eating too many special brownies.
Let me throw this into the works. A Kodak Brownie camera is something like a Singer 20 sewing machine; a cute little "baby" machine intended originally for children that happens to do its job quite well. Not so much of a toy but more like a CTID (child training/indoctrination device.) Any thoughts?
Only that CTID is a wonderful abbreviation I'd not previously encountered.
