Need info on Tony Gwynn Sportflics #13 and Topps Super Star small cards ...

mart

I have a 1986 Sportflics #13 of Tony Gwynn & I am wondering about the image ! I remember these from my youth but the ones I saw only had 2 images this one has 3 ! 2 of the images make a full swing and the other is his face !! Since I am not a card collector but I am interested in the hobby, I am wondering if they are all this way ? I thought 2 pics was the norm ! I also would like to know about the small cards that Topps made !! Are they worth keeping?? They are from the late 80`s ! Does anyone keep YooHoo cards ??? I have never seen them mentioned anywhere nor can I find them on Ebay !!!
