Fleer case numbers revisited

Thanks to Mike for reaching out to me about sealed factory case he owns.  The case is a 8 box cello case with all the standard markings but has an odd date code.  11089.  Doing some Googling I found pictures of other similar cases.  One has the exact same code. 

These cases appear to be very late run (Spring 1989) Grocery Store Display cello cases.   Supposedly inside is a Gary Carter cutout for display.

I can't explain the 5 digit codes on these but they do appear to be 1989 Fleer baseball.
