Need some help with checklists for 89 90 Canon Cubs

[cubman1941]

I need some help with Cubs Canon pictures. The TCDB shows only two years, 1987 and 1988. I have seen people advertise 1989 and 1990. I have four I got from the Cubs years ago and have them listed as 1990. These four are Berryhill – who is not listed in the 1987 or 1988 – Dawson who is listed in the 1987 and 1988 – Grace who is not listed in 1987 or 1988 and Walton who is not listed in either also. Thanks to some help I have received already, I have figured out there are Cubs from all four years but cannot find a checklist for 1989 or 1990. Does anyone know of checklists for these years? Thanks.
