anyone know the company name or even their website? would love to look them up & see what they have to offer
Sure; it's Abbots Hollow Studios.
The Etsy site doesn't really have much info other than contact info for the company. The guy I talked to at Gen Con was really nice. The two notebooks with faces I bought didn't have removable filler paper, so once you use up the paper, it's done. However, when I talked to the seller, he said he can definitely make ones that you can replace the notebook inside as custom orders. They're based out of Illinois, and the business card I got says they have a Facebook account, but I haven't looked at it yet.
