Installation disks for BusinessTalk System 2000 (AppleLink)

I came across 5,25" and 3,5" installation disks for BusinessTalk System 2000, a product by GEIS and Apple. The installation disks are from around 1992 by heart. Looking for any additional information online, all I could find was the wiki for AppleLink where BusinessTalk System 2000 is mentioned. A search on Google doesn't return any images of these disks. Can I make the community happy with some photos? Also, what would such disks be worth nowadays? I couldn't find any on offer online either.
