This was the first ever Spider-Man trading card set. It was released in 1989, a year before the first "all-Marvel" (Series 1) trading card set was published in 1990.
Five cards per pack. Not sure how many packs per box. Standard trading card size on white matte card stock. Packs were clear cellophane, no artwork. There are 45 cards in the set (including the checklist card), plus a "header" card that was included in every pack. No chase cards, no known promo cards.
Images were framed and titled on the front and all images were vertical (portrait orientation).
Low-res card scans are courtesy of fellow SpiderFan Celeste. I have purchased this set but it's still sitting at my buddy's house in the U.S.A. When I do get my hands on those cards, I'll upload some higher resolution images.
The back of the cards when assembled created two B&W posters featuring Todd McFarlane illustrations.
