I'm a peanuts collector for the last 40 years. The very first snoopy anything was 1958 and was cruder than the sample you have there. I'd say it's from 1967 as there was a big glut of peanuts stuff that came out that year.
I’d guess it’s an old fair prize, generally meaning unlicensed knock-off type... but that was just my impression with nothing to back it up except that it doesn’t look like the popular 1968 model.
