Blue and white isn't my decorating aesthetic (I really have none, mainly what I find at the thrift store) but I agree it's appealing. Blue is very calming.
I have 2 of these ashtrays from my Honeymoon. They were in our room and I was talking to the maid and said I thought they were soo pretty. She told me I could have them. That was in 1966, and I still have them.
