"Make Like a Tree... and Get Out of Here"

My freshmen don't like when I use that phrase.  I hope that the title made you think about one of my favorite movies - Back to the Future. 

I just found out that Kellogg's produced some Back to the Future cards in 1985.   Based on the article below, they might have only been available in Canada.  Does anyone know more about them?

Here is the article - https://www.beckett.com/news/back-to-the-future-trading-cards/

Does anyone have these cards?  I'd really like to find them.
