The ears...

I´m new here so I don´t know if you already have discussed this topic...

I can´t find anywhere in the books that the elves had pointy ears, the only thing I can remember of physical description was that they were greater than humans both to mind and body, and various haircolours..

But it seems that the common elf has pointy ears and is maybe taller but slimmer than a human.

Anyone got an opinion about this?
