Never seen anything like that before.
There used to be a helpful site, can't remember the name, its been awhile since it cared about cards instead of selling stuff, it began with a B.......
Looks like the tv warning system tests back in the day.
Maybe it is a ink test card or something like that. It's the 4 colors they use to print with. Where did you get it?
Judging by the angle of the logo, and the hologram placement on the back... a 2009 Upper Deck base set. I assume football as every other sport that year had silver foil for the logo.
I need help.
