LCD, and their branding (Arcade 1UP) all over the cabinets were the deal breaker for me. I understand why collectors go after them, but they aren't my cup of tea.
It was an "Imaginarium" rack from Toys R Us late 90's I got when I worked there. They were going to throw it out, and I saved it. Easy conversion of a very nice display rack. Just painted the base board and header black (originally white) and added the SMS sign atop. The red metal frame really stood out to me. I couldn't see it going in the dumpster.
I had to show some love for the Master System. It was my first gaming console I got for Christmas 1987 when I was 13 years old. Still the best Christmas I ever had.
I have a bunch more video game signs saved that were headed for the trash when I worked at TRU. The Super Nintendo sign I have above my window is one of them, circa 1995.
I remember the kiosk display of the SMS at Hills Department store 35 years ago, and could kick myself for not asking the manager if I could have it when they were through. I just remember it being very unique, and very cool.
