A generation ago I was in my teens and was so obsessed with arcade video games that I wrote letters to game manufacturers, asking about what games were coming out next. Many of them wrote back, and that's how my flyer collection started.
I only collect flyers from the first twenty years of the coin-op video game industry because 1991 was the year I stopped going to the arcades all together. I do own some flyers dated from 1992 and later which cover games that were re-released and sequels to games I loved in the eighties.
My flyer collection can be viewed at flyerfever.com.
As of June 2020, I have 3,950 flyers in my collection.
