Perhaps the club does have some programmes from the period you mention or maybe the owner of this batch does indeed have a few, but I think it's more likely that they were borrowed from other collectors in order to have copies taken. For instance, I have a City-supporting mate who used to collect programmes and has some incredibly valuable issues from the club's earliest years. I don't think he collects them these days, but no doubt his most valuable examples are tucked away somewhere for safekeeping.
