My son had a friend at daycare who was turning 5! Of course, all of the boys at this age are HUGE into Transformers. I too, once, was a huge fan. This little boy has a name that I am sure was not on a monogrammed bicycle license plate or a snazzy little WB mug or toothbrush. So, why not a personalized stamp? It turned out really neat. I found a little starter kit at Michael's and I think I am addicted! My son already expects his to have "The Batman" on it. How precious is that.
