If for some reason you are interested in Belarusian billboards (and why wouldn't you), here's a fairly large gallery. This is my favorite billboard for heavy farming machinery by Gomselmash under the slogan "The Pride of the Country". The collection of the social billboards with a healthy mix of state propaganda is also very nice.
This one with a cute police (actually, militia) officer reads: "Call us to defend your rights." Speaking of rights, here's an earlier post about a campaign in Poland to defend freedom of speech in Belarus.
A somewhat morbid billboard that (I guess) warns against the dangers of speeding and says "Are you in a hurry to reach us?"
