Theese are NOT viking runes. They are an older Rune alphabet, from around year 500 and earlier. They are called the elder futhark. The viking Rune alphabets have usually only 16 runes and there are several different alphabets from that time.
Runes and the English letter values assigned to them by Tolkien, used in several of his original illustrations and designs for The Hobbit. << My friend taught me this alphabet a bit. I was fun to write to each other!
