Has anyone seen this type of slab before?

I just got this card and I am not familiar with BGS slabs. With the limited amount of BGS cards I have purchased, I have never seen one with this type of flip. The front is normal, but the back appears as though it is personalized. Who is "Schonco Sports"? Has anyone ever seen a BGS flip like this? Based on the seller, I am presuming it is a good card, slab and flip, but I wanted to get some opinions. Thanks.

Schonco was one of the biggest basketball card dealers in the 1990's. They dominated the market in high grade 1957 Topps and 1961 Fleer cards.

The card and the holder are good. No 3rd party grader was grading Star Basketball for a while. The Schonco Star cards were the exception. At first Beckett only graded Star from this collection. They are now more comfortable in grading Star and anyone can submit Star to Beckett now.

Thanks guys for the information. The nice thing about these boards is the amount of knowledge on here. Always glad to learn something new. So that flip appears to be a sort of a pedigreed notation. That is a cool bonus to my addition.
