First off, kudos to the kid for thinking quick and welcoming the new guy to town. But masking tape? Black Sharpie? Really?
Even though it would clash a bit — but still be better than the current product — I think I would have gone with a blue painter’s tape to cover up the old name and number. Then maybe use some Wite-Out for the letters and number, and then get a bit of yellow and blue Sharpie in there for the trim.
Not that I put a lot of thought into it or anything. — Bryan
