@Azuza - Well, not all salvers are unassuming. I saw one at a dinner party a little while back that was very decorative.
It had feet, and the whole thing was covered in decorative etchings. It looked expensive and I could tell the hostess had it out partly as a conversation piece. And, what do you know, someone took the bait and asked her about it. I had never heard of a salver before then, so that was my fun fact for that day.
