I hadn't even noticed the reflection, it is kind of creepy looking. - even if the beaker isn't too old it'll make a neat halloween decoration or for wine like Bostaurus said. Mmmm Wine.
Hi and welcome.
The acid bottle looks "acid etched" but it's not that unusual, just darn cool. I'd guess 1920's or so. The inside neck should be ground to fit a stopper.
The odd one looks like an applied color label lab bottle and more recent if I'm right, maybe 1940 and up.
The "warranted" flasks are nice and maybe the oldest but quite common.
They're all interesting to me but probably not uncommon.
That's just my opinion.
