'I gathered this information from Wikipedia, so if it's wrong.....  "The Looney Tunes Golden Collection unequivocally credits the vocals to Bill Roberts, a nightclub entertainer in Los Angeles in the 1950s who had done voice work for an MGM cartoon earlier."

I loved this character from the first time I saw the cartoon, I was three. I didn't know until I was older that this was his one and only cartoon and that he never even made a cameo in any of the other Looney Tunes cartoons.

I started collecting him as early as I could find his image in stuffed toys, pins, etc. My sister ran across a collectors plate with a copy of one of the cartoon cells and bought it for me. When I first started collecting 'him' most people didn't know who he was. It was just my totally engrossed obsession with the character that made me aware of him.

As a side note, I started collecting all kinds of frogs - live, prints, statues, cartoons, etc. at an early age, so this may be why I became attached to Michigan. I have a huge collection of the little critters because I became associated with frogs and everyone knew they could buy me a frog something and the present would go over well. I have actually bought very few of these items myself. To my amazement, in these years, there has never been a duplicate. Think of the odds.
