I actually took a closer look at the tower after I got it home, and the signs on the tower that I want to remove are actually stickers that I should be able to carefully remove.

I just got one of the Walthers built up interlocking towers. How do I remove the lettering (the big BX and the numbers) so that I can add my own?
