Cameron Blue Tulip and Franciscan Metropolitan Tea Things

A while back I decided I wanted to start having "tea". Usually I just made tea in a mug, but I figured it would be nice to use a real teapot and fancy teacups. I have found some interesting pots and cups here and there at thrift stores. What I wanted to share today were a few cute finds in robin's egg blue. They aren't a matched set, but I don't think you need to have all pieces from the same set.

The pot below is either Cameron Blue Tulip or Cronin Blue Tulip (debated). It is a mid-century piece and what a darling teapot it is! I liked how it looked Danish, and the design was so cute and contemporary, I initially wondered if it was new. The only clue I had was that the unglazed clay on the base looked old and somewhat worn, and that it looked it like it had sat in a garage (was dusty). I got it at Goodwill in pristine condition, for only $3.99. The Goodwill is notorious for being overpriced, but as I always say, they slip up sometimes and price things reasonably!

The other two pieces (creamer and sugar) are Franciscan Ware Metropolitan, circa 1940. These are new finds I picked up at the hospice for $3 apiece. I thought that was reasonable enough. I see Franciscan from time to time, mostly the rose or apple patterns, sometimes Coronado, but I have never seen these!

I had a hard time finding others online as comparisons, and very little info was available. One seller had matching plates and cups in this blue, and one person had the matching tea pot in blue, and there were a few sold listings on Ebay. They also had a line called Tiempo which seem to be the same molds, but different colors (and it seems Tiempo was made a few years later). Are these really rare? To my understanding, production was limited to a few years, and of course, they are early pieces.
But of course, I got them because I just loved the shape and colors!
