To avoid overfamiliarity, I created five posters: four highlighting specific product aspects and one tying them together.
The idea was to strategically place the four posters in high-traffic areas; places that employees walk past but rarely linger. The fifth “summary” poster, composed of titles and no details, would reside in the employee break room or another location where staff gathered.
Employees would likely see the summary poster first and then, later, one of the more specific posters. This would spark their curiosity and -- best case scenario -- inspire them to hunt for the other advertisements.
