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.
When I'm calling. Telephone Sheep by artist Jean Luc featured in a Frankfurt museum. A flock of sheep made from old rotary phones. The "wool" is made of phone cords. Fabulously creative and if you blur your eyes, they really DO look like sheep!
