1988-92 Star Ad Cards Baseball Forum

I think this is an ad card for this set:

https://www.tcdb.com/ViewSet.cfm/sid/190542/1989-Star-Sam-Horn

If so, should it be added as another promo?  Or is there a separate set it belongs too?  I see there are examples where Star promos and ad cards were given their own set:

https://www.tcdb.com/ViewSet.cfm/sid/193528/1985-Star-Promos (it seems these are not considered promos of their 1986 sets)

https://www.tcdb.com/ViewSet.cfm/sid/157272/1988-92-Star-Ad-Cards (these ads do not advertise a specific set on the back)

I also looked at a few other 1989 Star sets and I don't see similar ad cards listed as promos (not sure if any exist).

Thanks for any help!

Seems like it belongs in the 1988-92 set

1988-1992 is where this would go. It was produced in late 1988 or early 1989. Star Co, Ad Cards were never released in conjunction with specific sets.

Thanks for both of your confirmation.  I wasn't sure since all of the other cards there so far didn't seem to be for a specific set like this one.
