Nectar Tea's advertisements are generally found in the iconic teacup and saucer format - this layout is a lot less common and can be found in dark green, blue and red varieties like the above. Generally this example is dated to around 1910-'20 making it a lovely early piece and in my experience fairly unusual. 

 

This particular example remains in absolutely fantastic condition; the red background remains vibrant and the condition is as near to perfect as you could hope to get for a piece from the early 20th century with absolutely minimal enamel loss, even around the edges/mounting holes. 

 

The sign measures 76cm (30") wide x 50.5cm (20") high and displays beautifully using it's original mounting holes.
