There's one on eBay right now with a BAM sticker on the front and an autopenned bookplate inside.
Edit: When BAM put up the note about the second batch being bookplates, a lot of buyers of that batch reported receiving tipped-in pages. Those tipped-in pages were good.
I suppose if you're reasonably close to a BAM store and it's of interest-you can roll the dice and can always return to store. The coupon zeros out most of the shipping.
Personally, I'm good with my non-bookplate version.
Here's an example from eBay. The AutographedBooks sticker is exclusive to BAM. You can find exact copies of this exact same autopen signature in posts from last year and eBay listings.
Maybe he signed new bookplates this year, you never know. Just stay vigilant.
