Hey yooooooooooooo! Nice job!! You're going to make me take pictures and post the sets I finally finished from that season, aren't you? **Thumbs up**
Right! 87-88 indeed.
The team used really thin numbers for the first half of the season, with any of the shoulder numbers having yellow/white color filling in any of the loops in the digits (with the exception of 0) depending on if they were home/away jerseys. After around some time in early February, they switched to rather thick numbers, and the shoulder numbers had any of those digit loops open up. The C/A also were different between sets, again growing in size for the later half of the season, and a 2-layer press just like the numbers.
A few examples:
Oct 87 - Feb 88:
Feb 88 - End of Season:
The 2nd set black jerseys were really hard to find detail for. I had to resort to mostly video, which I have at home. All cards and nearly all photos I've seen are from the first half of the season...which is a shame, because I like the look of the late season kits.
