Nike produced its Jordan poster cards as trade pieces — small cards distributed to retailers to catalog the full-size posters Nike was shipping, marked ‘For Promotional Use Only · Not For Resale.’ They were never sold at retail. The Reverse Dunk card, Nike catalog #290909, references the 24″ × 24″ poster of the same name, released in 1990: Jordan stretched fully horizontal in mid-air on a hardwood court, finishing a reverse dunk with arms and legs extended. The pose is often noted for echoing the outline of the Jumpman silhouette — the body splayed in the air the way the Air Jordan logo renders it. Across all grades, 40 copies have been graded by PSA, and only 4 have received a PSA 10. DimeLabs owns one of those four.
