Vintage Mackinac Island Intaglio Style Blue Charm Pendant w/ Horse Carriage Taxi

Description

I have hundreds of pieces of fine and vintage costume jewelry that I'll be listing when I can.
This listing is for a vintage charm featuring a horse and carriage from Mackinac Island Michigan:
it is done in the intaglio style (the design is engraved under the lucite dome)
It's in good condition but needs a cleaning around the lucite
the little bezel/loop that fastens to a bracelet or necklace is worn and no longer shiny but the charm is shiny
measures almost an inch in diameter
unsigned by any makers
I believe it's a few decades old but I do not know it's age
I don't clean all pieces because some I'm afraid of damaging but most are wearable and need only light cleaning or are fine as is, I'll try to comment on this in each listing.
I am also selling items for a gentleman whose wife recently passed away.  She was an avid collector of Hummels, Royal Daulton, Elvis items and much more.  I'll be listing a ton of items for several weeks as long as I have no interruptions.  :)
Since I'm not selling for myself I do have to charge shipping on most items, I hope you understand.
Thank you very much for looking and have a good day!  Please view my other items - I gladly combine items for shipping whenever possible.
