I'm considering selling a fiber optic sign I have. The Nintendo logo is displayed on both sides, only one of which lights up like a Christmas tree. The model # is NESM36F and it measures about 32" Wide - 12" Height - 6" Depth. I want to say it was manufactured in 1989 since many of these kinds of signs were, but nothing on it seems to suggest a date of manufacture. It's in good working condition - it has some light scratches on the sides with heavier ones on the bottom.
Here's what it looks like:
If anyone has any questions, I'll be happy to answer them. If you know anyone who might be interested in this, please let them know about this.
