I found these vintage plate sets at Goodwill a few years back...
I got three cups and three plates for a grand total of $1.99! Such a bargain!
I love the cloud/amoeba shape of the plates and the ring that actually holds the cup in place.
The cups themselves have the same pattern and little raised ridges on the handles.
My kitchen is actually quite modern and these don't really match anything else but I find them adorable! I have no idea who the vendor was and I probably shouldn't but I put them in the dishwasher and microwave all the time. But they're still in amazing shape. The decal on everyone of them is perfect!
