This 9-1/4" transferware porcelain plate was printed in a very dark blue in the pattern known as "Curly Pagodas" or "House Boat". The border pattern is called "Trellis Diaper". Michael Messenger discusses and illustrates the pattern on page 65 of his "Coalport" book. He credits the first use of the pattern to Thomas Turner of the Caughley Works.
The plate is in excellent condition. There are no chips, no cracks, no crazing and no repairs. The plate rings when tapped.
I have other pieces of this partial set bearing Coalport's distinctive impressed numeral "2". That mark was used c 1815-25. This plate was incompletely impressed with that number. I was not able to photograph the faint mark.
I also have a sugar box and 8 matching small plates available. The plates are offered and priced in sets of two.
