Where can you buy the mini statue of Vince Lombardi that the packerproshop used to sell?

Your best bet is to check auction sites like ebay or even look on Craigslist.

There was a limited number of these statues made. I believe it was 1000 of each Lombardi/Lambeau of the 18" and then maybe double that amount for the 12" sizes.

I saw a pair listed on ebay about two years ago and they were asking $4,000 for the set of 18". Both sizes are made of bronze.
