This Heineken mirror beer sign must be, at least semi-rare. I have had 2 of these for about 25 years and periodically checked the internet and still to this day, have not seen one exactly like this. The colors of red, black and green within an oval are out there but scarce. And the initial of “HBM” inside the star,  I have never seen. It measures 13 1/2” x 13 1/2” I would consider the mirror to be in very good condition. Far from perfect but nothing major that stands out. However, the back is kind of a mess. Whoever purchases this, I would suggest removing the staples & nail in the back a reattaching better.
Thanks for looking.
