Welcome to the forum , ErinH .
I'm curious to know how much liquid your item will hold , since you call it a milk pitcher ?
I don't recognize the mark , but I'm no expert on most cermaic marks .
I've seen 'imitation' delft items that folks buy , even knowing that it's only the 'style' of delft .
Who knows (I don't) , maybe 10 -20 bucks ?
Maybe others here will know .
Not a bad-looking creamer , actually .
