You'll see them all sorts of patterns and colors. I have a neat round blue one I kept for myself. It has sections to put divided parts like cheese or little plates of things. Very mad men and serving with it always brings up interesting conversations. I haven't used it much really. I may sell it I don't know.
But the one I have up for sale now is really lovely and oh so retro! Well, it's vintage not retro but these words seem to mean the same these days. What I also love about them is that you don't have to use it to serve things. You can use on your dresser to hold your perfumes ladies. In the kitchen you can have leaned up against the wall as lovely decor. You can hang it and really just about anything.
Here is the description and here is the listing.
