Don't laugh....but, back in the mid 1990s, I decided to make my own cards using posterboard and markers. I made quite a few of them, but I didn't concern myself with such things as proper spelling, staying in the lines or anything near even cuts along the edges.
I even made at least one paralell!
The time was mostly 1995, but some were, I think, 1994 as well.
Each card was a one off. I did number them but I put two different numbers on most of them, and I don't remember which one was the card number and which one was something else. I also didn't number them in order of making them, they were just numbered randomly, like you get when you open a pack.
The only criteria for getting a card appears to have been, there must have been a 1/64 car of theirs in my collection.
I was about 10 or 11 when I made these, depending on the time of the year (I have no idea when)
