M17B
Does anyone have a M17B sign that they can take a photo of the back?
I picked up what I believe to be an M17B (the dimensions all match, and seems to match photo) but get the feeling it had something on the back side that is missing

They are supposed to be double sided. Same front and back with hollow core.
^ Yup!

2nd edit: I just measured my sign as well. Yep, it's the M17B and mine is the same side as yours.
M17A - An 11"h X 48"w 2-sided hanging sign of the Nintendo logo.
M17B - Logo Display - Nintendo Vacuum-formed Logo (one sided). An 8"h X 30"w one-sided header featuring the Nintendo logo. The reverse side is black liner with a printed logo. Ships with brackets to fit peg board or slat wall.
Confirmed measurements when I got home, its 8 1/2"h X 32 1/2"w
