This sticker isn't an electronic item, but you could FIND it on electronics...specifically MegaDrive games. This sticker is a public service announcement that was stuck onto various games (ddin't have to be Sonic). It has a slightly modified Knuckles stock art (they've moved his eye & slightly re positioned the back fist, but kept him otherwise pretty unchanged) He's shown punching a pack of cigarettes (pack says Nicotine on the front) the slogan "Smoking - who needs it?" is at the top. (not the best slogan, as "who needs it" is the unfortunate people who got addicted to this drug!) Look at the hotline number prefix, it's from the UK. This was made for a "summer tour" at some point in 1995. Info added by Fizzycat
