I donated about 50 issues of Wheelspin to a guy who said he represented The Canadian Motorsport Hall of Fame around 2000. These were from 67-69 if I recall correctly. He told me I would get a tax receipt in the mail, I never did. I have no idea now where they ended up.
I volunteered with the Canadian Motorsport Hall of Fame archives back in 2001 for the summer. At that time, they were trying to organize all the memorabilia that was donated- programs, pictures, drivers helmets, suits, etc. I did not come across many Wheelspin newspapers then, maybe they were still in boxes. There was a ton of stuff that had to be looked at. I came across lots of Road Racing items, but not much Stock Car programs or pictures.
The people running it had very good intentions but it was all volunteers with not alot of funding. Everything was treated like gold so I'm sure the Wheelspin collection is still around.
