Just something from the time of the Zodiac killer era

My mom now lives with me …she is in her 90’s.
Our old home is vacant and I take care of it . the other day I was getting some 22 ammo still over there, some from the 70’s .
In a upper cabinet, way in the back , in a box was this 750ml Crown Royal whiskey . the date bottled stamp reads 1965
In the bag it was in was a very faded paper receit, using a magnifined glass it is from Milgrams Liquior store it costs $8.79
and pretty sure the date was July 2 1969
We had neighbors and their kids come over on the 3rd and Dad bought it for that.
