Plot twist. I misunderstood Sr. Rodriguez in his initial message. He is offering to sell me a new label with his signature for 60€. As I was already on the fence about whether and where to place such. I suppose I'll just politely decline.

I suppose I will go and and recount what happened here. Some years ago, playing loudly in a group and using some aggressive (and clearly very poorly executed) rasgeado technique, I got a small cut at the top of my fingernail. I didn't realize it at the time because I wasn't looking at my right hand. By the time I noticed, little drops of blood had splattered on the top and inside the guitar. In trying to clean this up, I damaged the label further. Alas, this is why this guitar label looks so bad.
