As PDBLAKE stated, Feanor's emblem is on the back cover of The Silmarillion. You should be able to find versions on some of the Tolkien web sites. However, the ships he used were stolen from the Elves of Alqualonde whose emblem was the swan. Any maritme emblem would be appropriate though. The dragon is not. Dragons were created later by Melkor & would not be used as an emblem by any Elves. :) Keep at it... its getting there.
