I tried not to impose too much on his generosity by claiming only so many cards - my favorites are probably the Mike Schmidt, Fred Lynn oddball, Bo Jackson promo and the Topps rookie year subset feat. Shohei Ohtani / Ichiro.
As much as I've read Nick's blog over the past 5-6 years, I just have not interacted with him like other collectors who may do trades and /or send him stuff [and vice versa] - besides the cards, it was nice touch to personalize things with a short note.
