The first newspapers had to be chisled out by hand with a chisle and mallet. Not exactly the fine print we get today. And if the chisle-er made a mistake, then that piece of stone would have to be reprossessed. This would cause a delay in production and delivery. Another drawback was that those stones were heavy. And no matter how greased your cartwheels, the donkey could only pull so much weight. However, if you were lucky enough to get a copy of The Evening Stone, (at the price of only three dracmas per slab) you would have a piece of news that could literally last longer than a lifetime. (pardon the alliteration)
