What's the meaning of the letter?

I find I usually need to go to both the art of the tag page and the color swatches page to verify that a bag is authentic.

You can just go to the color swatches page if you want to verify that a particular color was produced during a certain season letter ... the correct season letters are posted above the color swatches for each season. Here is the color swatches page:

No problemo - love your avatar, badbananagirl! ;) Do you have the big photo posted somewhere so I can see a closeup?

Does anyone know what letter will the Spring colors have? Will it be "V" ? Why did they skip "X", by the way?
