Billboard ads are one of the most effective way of making an impact on the minds of the consumers through witty slogans and sharp punchlines. Billboards(huge in size) are usually stationed on highways and,or high traffic areas so that they when read ,make an indelible effect on the minds of readers so that they remember it thus aiding and influence in buying a particular brand of products.
This is an old billboard ad of Hallmark, quite outrageous in its statement thats why was withdrawn never to be seen again.
