Very interesting old bottles!
The Sauza bottle, looks like it is an older bottle probably from the late 70s early 80s. This was actually a mixto (51% as opposed to the current version that is 100% agave distillate). The bottle does not say Anejo but I am quite sure that the age of the tequila was over a year in barrel.
The Canadian Club from 1984 seems to be intriguing. As you may know it is a blended whiskey with a higher percentage of rye from of course Canada (although I believe not all the whiskey is made in Canada). As blending goes, the master distiller that put this together may have passed on or definitely his palate has changed. The older bottling of Canadian Whiskeys altogether has become sweeter in style as evidenced by Crown Royal. In Hawaii, we probably rank as one of the highest per capita Canadian Whiskey drinking population with many of our residents being of Asian ancestry that love their Whiskey, but more of the blended types such as JWalker Black, Chivas, CC, and Crown. We regularly come across old bottles from the 70s of Crown and J Walker and we try them out finding that the older bottling seem to be drier but with a hint more complexity. The previous post correctly mentioned that it does stop aging once placed in the glass, so it is like a glance into the past! In our store, we have even come across one of the oldest bottling of Johnny Walker Red in the world (see the article:
http://tabletalkhawaii.com/2010/09/the-long-journey-of-johnnie-walkers-striding-man/ ) that we donated to the archives in Kilmarnock, Scotland. Take your time and find an occasion to open up one of these bad boys with some good friends, good times and of course some good cigars!
Cheers!
