Following Apple’s original founding documents being auctioned for roughly $1.6 million at a Sotheby’s auction on Tuesday, Engadget sat down with Apple cofounder Ronald Wayne who shared a collection of other early documents related to the company.

The report noted that Wayne has the documents stored away in a USPS envelope in his office, some of which include hand drawings in pencil for an Apple I casing that was ultimately rejected.

Interestingly, Wayne also has a copy of the founding documents that sold at Sotheby’s, as well as the document that he handed in when leaving the company. Other interesting documents in the collection include an Apple I manual with Apple’s original logo designed by Wayne, and a purchase form for the Apple II.

It’s safe to assume that these documents could also fetch a pretty penny if Wayne ultimately decides to put them up for auction.
