Marvin Acme's will

Marvin Acme's Will is a piece of paper wich had the will written on it with Dissappearing/Reapearing Ink. It is one of the main plot elements of Who Framed Roger Rabbit because, according to Baby Herman, it is what benqueths Toontown to the Toons, and if it was not found at midnight that night, Toontown would be in the hands of Cloverleaf Industries and it's owner, Judge Doom. Later, Valiant discovers the will in Acme's pocket in one of the Patty-Cake pictures he took earlier. Then Roger shows up protesting his innocence and reveals a love letter that he had written for his wife. Eddie figures that the love letter might be a clue, so he keeps it until the toons show up at the Acme Factory at the end. Roger then discovers that he had written his love letter on Acme's Will. It reappears and Roger reads it, revealing Acme had left Toontown to the toons.
