The auction markets are really pushing the Brett Favre memorabilia. The World of Sports blog has a great article about this.
If you're looking for Favre memorabilia pieces keep in mind:
- The sellers feedback rating and reputation
- The quality of the autograph itself
- The quality of the memorabilia the autograph is on - look at both independently
- Is it PSA or JSA authentic?
- Do you receive a photo of Favre signing the item
