It's your bike of course, so if you want to remove labels, do as you wish. I've removed labels off mostly modern rims as I deem them aesthetically appalling. As is "www.whatever.com" stuck all over the bike. The rims you have are desirable and well made. As others have stated, you may reduce their value by removing the label on these due to historic value to collectors. I like the idea of placing them onto the inner wall of the rims if you do decide to peel them off.
After reading here I will leave the Mavic labels on. I have always been one to pay a lot of attention to detail. I just regret now that I took the labels off of the Campy wheels. I'll not do that again.
