What exactly is this "tv card"?
The word "TV Card" was the only word associcated with describing it. It's thought that it was like some kind of ad-card or something, likely dispensed in a magazine, a booklet, or some kind of leaflet-thing (as in, an ad card inside a video sleeve or something)
The logo at the bottom of the TV says "Amazin' Adventures" over a kind of squashed globe shape. Its clearly advertising the weekday Adventures of Sonic the Hedgehog cartoon, with cartoony running Sonic & Robotnick chasing him with the spike ball in the 'egg o matic'. This was made back when it seems they were trying to still be convincing that the show might have a tiny something to do with any of the games/familiar imagry. Whatever this item is, it's interesting to see the early ad efforts.
