Printed rulers for rulers?

If Caesar was around today he'd embrace every form of advertising possible to promote the merits of the Roman Empire. The vast array of various products on offer today could well have been to much of a temptation to simply disregard them. He'd want to use the products which could be seen everywhere and were common place with practical usages as well. Keeping in mind the Roman love of all things straight like their roads for instance, I'd have thought that promotional rulers woud be among the leading candidates with their long straight edges and equal measurement increments.

Alternatively, some other rather well aligned products that may have taken the fancy of this notable ruler could be printed desk pads and promotional folders and perhaps balmoral pens. Either way the concept of promotional yourself to the maximum with printed products is a great way to ensure awareness of your message.
