A sealed (new) Chicago VII came with a green sticker denoting SQ Quadraphonic. As depicted above, there is no Quad marking on the front cover. I posted a photo of VII SQ 2 LP version w/green sticker as post #4 in the QQ Chicago VII Poll: https://www.quadraphonicquad.com/forums/showthread.php?20455-Chicago-Chicago-VII-SQ-Q8 A picture of the 2 Q8's w/box is also depicted. A sealed 2 LP 2ch VII would have a blue sticker, BTW. Either LP version would have an embossed cover, which the Quadio jacket replicates.
An SQ Chicago VI would have a textured cover, emulating currency, just as the 2ch LP and Quadio VI jacket has.
