I saw a signed books from Premiere Collectibles on eBay, is it authentic?

Due to their collectibility, thousands of signed Premiere Collectibles books trade on the secondary market each year, often at premium prices. There's a good chance that the signed book you're seeing on eBay or elsewhere is authentic, but use your judgement. Check the seller's feedback and look at the other items that they are selling to see if you notice any red flags. You may be able to message the seller and ask them if they can provide proof of purchase from Premiere Collectibles (if the seller is charging a premium, you may want to acknowledge that you understand that the price shown on the proof of purchase may be lower than their asking price and that you're only interested in confirming authenticity).
