1951 Topps Red Backs Baseball Forum

My question is this, for the 1951 Topps Red and Blue Back cards in the 2 card panel form, did they come that way out of the 2 card packs, or did they come that way when sold as a comple game card set?  I have bought two packs of 1951 Topps in the past, and the cards I got were separated and not with the card it should be with on the panel, so I assumed the packs were actually opened and resealed.  In both cases the seller gave me my money back.  Should they have, or was I wrong to believe that the cards come connected in the 2 card packs?

They had penny packs with the 2 cards stacked without perforations or in panel form and without standardized pairings.
