1988 Topps Baseball Forum

I have two different versions of the "Glossy Send In" cards, neither of which has the arrow or the "cards not included" message. 

One has the white back like is pictured here: https://www.tcdb.com/ViewCard.cfm/sid/125/cid/6008878/1988-Topps-NNO-Glossy-Send-Ins-Offer

The other has a gray back.  The gray back looks like this card, but with the Glossy send ins on the front: https://www.tcdb.com/ViewCard.cfm/sid/177664/cid/6890113

19/52 of my cards are gray back, the rest are white back.  Both have identical writing and none of them have the arrow or "cards not included"

The gray back version need to be added to the set.  Is this a variation, or are both the white back and gray back considered variations?  Currently the white back card is not listed as a VAR in the checklist, but all the arrow cards are listed as VAR.

Finally, all of the cards are linked to the Cardinals, but none are linked to Jack Clark.  Should the Cardinals link be removed, or Jack Clark added to all of various versions of the send in offer?

Wow - this is a lot of work for a send in card worth nothing.

There's also a blank back version in Topps Big

As for the white/gray, I haven't researched yet to know for sure. Possibly the type of pack they came in?

Both types came in generic wax packs.  I got a few boxes as rewards for my kids a while back.  That was a lot cheaper than current cards.  I have multiple copies of both versions, all from wax packs.
