Was wandering in NYC yesterday and walked by Fishs Eddy's and stopped in my tracks. They had a window display showcasing sample china plates from Syracuse China.

Before producing plates they would cast a sample to check color and placement, and then show the client.

I loved them! Combines so many of my antiquing loves: dishes, antique writing, industrial, one-of-kind items...

I found a few salesman samples on ebay.

But they were pricey! and none as amazing as these. So I'm on the hunt!

And this one tests logos:

I found these images from the Restaurant Ware Collector's Network.
Let's hope I find them while antiquing!
