Recently I came across a pair of game worn shoes worn by a star NBA player. They were signed and showed nice usage. When discussing the shoes with the seller I discovered that he wrote on the shoes after acquiring them. He wrote the date and score of the game in which they were used and the writing took up a good chunk of space on the shoe. Hard to miss. When I found this out I was shocked. It would never occur to me to do such a thing. After finding this out I wasn't interested in buying the shoes anymore.

Does anyone here have an opinion about this? Is this a normal practice?
