My wife added a small amount of art to her helmet, back in the '80's.
The name of her car was "Born Again". The butterfly is a symbol of new life. So, along with her initials, "TJ", which is what everybody has called her, for most of her life, she also put a butterfly on her helmet.
In pic #2, you can see that she also put a small butterfly beside the car name.
And in pic #3, she also put a small butterfly beside the scripture verse, on the trunk lid, which represents the "New Life" one can experience after being "Born Again".
Hey, this is a great time to post this, right before we celebrate the birth of the Savior !
