When my Kids were teenagers they painted the basement grey, mottled yellow over it and then my daughter painted a HUGE dragon bust with crossed arms. Dragon is purple and green with yellow, red and gold gilt-type paint accents.
Glad it's in the basement. Sad it's on a wall and she can't cut it out and take it to HER home. It is really well done, she is quite the artist. But it just isn't my style. <sigh>
