Cartoon character with a big nose beginning the letter L ending vig?

The cartoon character you're describing is most likely Long John Silver from Robert Louis Stevenson's classic novel "Treasure Island."

Here's why:

* Big Nose: Long John Silver is known for his prominent, hooked nose.

* Begins with L: His name starts with the letter "L."

* Ends with Vig: "Silver" ends with the syllable "vig."
