Next we will look at Type 4 since KC assures us that chronologically that was the next type that was produced.
This is the blank backed grouping so through the decades it has been the most mysterious of the 4 groups. We all knew they belonged in the set but why in the world would anyone issue them without and product code or title ???
Now that this paradox has been explained by KC lets take a look at what type 4 was all about.
As noted in blog 76 in late 1987 a new director was hired for the retail poster program who chose to use a less costly, thinner paper stock and left off the poster descriptions off entirely (cheaper if you don't have to print on the back ). The posters already lined up, i.e. Mike Schmidt Superman, Lethal Weapon, Supreme Court II, Mr Barkley & Earth/Mars) were given product numbers 290870 - 290874 continuing where "Ohio Flyer" left off......and thus type 4 was born...
At this same time (1988) Strange Thoughts (291543) and Hit and Run (291621- 2 poster cards), created by the advertising team in late 1987 were also added to the retail poster list without changing the product codes assigned by the advertising team, thus the 291XXX numbering that has puzzled us collectors for so many years..
They then decided to "back fill" the poster code gap and went back to 290811 for Mark Jacksons "Home Town" in 1988 and finishing with 290819 "Cycling the Golden Gate Bridge"
Again they added advertising poster "Big Guys" 291776 and "Picture of Fitness" (the mysterious female athlete leaning into the Greek Column) keeping the advertising product numbers.
Many of these were reprinted in 1989 with descriptions on the back (type 2) when management turned over again in the summer of 1988.
This accounts for 30 different type 4 NPC's which had subsequent reprint variations. This is all depicted in the revised checklist printed below for Type 4
TYPE 4 290870 - 290887 (1988)
Type 4 TYPE 4 290811 - 290819 (1988)
291776 , " Big Guys" and the female Athlete on the Greek Column poster 291857 (officially called “Picture of Fitness” by Nike) were discussed in blog #60 although their Nike Numbers were not known. As we pointed out they retained their advertising numbers and were not given numbers that chronologically fit with the rest of the group 4 NPC.
