What date range would you categorize a picture that was printed on “Konica Long Life 100” paper?

We have an older picture that we’re trying to see if we can pinpoint more or less what time frame it was taken in. It has no date on it. Thanks!

Scotts answer tops; without the packaging you have a quarter century margin to work with. If it was best quality printed, and stored well, it may exhibit next to no fading even if it was mid 80’s and I doubt you can tell any colour shifts either. There may be a forensic way to tell the age (tests on traces of fixative or bleach wash) but we’re talking FBI lab here, VERY costly unless you know someone in the trade. Why it matters, pray?...
