I picked this up at an estate sale of someone who was a collector, not being quite sure exactly what it was. It took a while to find the espresso shot mirror and its likeness to my item. I can’t imagine it’s anything else.

Although I was unable to locate one made of similar materials, or one produced in the same era, perhaps it’s a very early version of the product itself.

I believe this to be a very unique item, and it is priced accordingly. If you happen to have more information, or have seen this item used for a different purpose, I would very much appreciate any information.

“If you have a bottomless portafilter, you know why an espresso shot mirror is handy to have. You want to enjoy the show of your espresso extraction but your neck or back starts to get sore after a while. You can only crouch so much! That's why I'm listing the best espresso shot mirror for your espresso machine.”
