This is a lovely vintage 1940s Czechoslovakian double open salt, salt dish or salt dip in the Blue Onion pattern.  

The elegant blue and white fine porcelain double salt was made in the 1940s by C Teichert, Dubi', Czechoslovakia in a variant of the Blue Onion pattern in flow blue transferware.

The handled double salt measures 2.25 inches high at the handle by 5 inches long by 3 inches wide and is in very good +++ used vintage condition with no chips, cracks or wear.

So cute! The little salt dish would also make a great teabag caddy, ring dish or cream and jam on the tea table.
