Lady and unicorn round jigsaw (Gidea Park RM11)

This one is for someone who likes a challenge. It's a Past Times 500 piece double sided 19 inch round jigsaw. Luckily you can tell which side you are doing as one side oh the pieces is more raised than the other! The top picture has faded in the sun. The other on the bottom of the box is ok. As far as I know all pieces are there but no guarantee! You can also find this lady and unicorn picture online as it's well known - "My only desire"
