Creative Bar Mitzvah Invitations

To design an invitation postcard for a Bar Mitzvah celebration. This invite would have the invitation on one side. On the other side of the card would be a portion of a larger line art image of my son (possibly derived in part from a photo) plus a few elements symbolic of his big day. each guest would be invited to colour in or otherwise complete the card and bring it on the day to co-create a lasting gift for my son.
