I found this tin at a yard sale and bought it for my mom. Velvet tobacco is what her dad used, and she and her siblings would cut the cans up and make whistles. She actually got one of these tins a few years ago and couldn't resist taking the snips to it to see if she could still make one of those noise makers. She did do it, but was sorry she had to sacrifice the tin. I saw the whistle and heard it, but I can't tell you how to do it. I will ask her next time I'm home, and hopefully get a picture of the one she made.
