Lately, we have had a chance to see a considerable amount of guerilla examples coming from Balkans. However today I am coming up with an eye-catchy example which has been actual for some time in Novi Sad, Serbia. This time, the floor is given to guerilla billboard in Novi Sad.
Translation goes as following: The billboard is currently empty. We have booked the termin but our designer got stuck on his vacation.
The billboard itself was intended to promote anonymous travel agency Elnos Tours and their summer offer in a funny and catchy manner.
You draw your own conclusion how effective it is.
