This Haviland design is pictured and described in detail on page 135 of Richard Lukin's 1990 edition of "Dining on the Rails". The yellow, green, and pink Spider Mum design was described as a very fragile, delicate pattern that was thought to have been used on the business cars of the Chicago Burlington & Quincy Railroad. Business cars were used by executives and the equivalent of modern day corporate jets. This Haviland pattern has been assigned Schleiger number 492A which consists of pale yellowish green flowers, resembling spider mums, with brown outlines and a faint touch of pink. There are also bluish green stems on leaves touched with pink. The pattern has a definite Art Nouveau aesthetic. The effect is stunning. This pattern also has the factory number 19460 and it was produced on Blank 204. It is marked with the double Haviland factor marks as shown. Lukins states that it was sometimes backstamped with the CB&Q logo. This piece is not. The identical design was also made for home consumption and we can not verify that this pieces was used on the railroad. The oval platter is 11 1/2" long and 8" wide. It is in excellent condition with no cracks, chips, or repairs. There are not utensil marks. It was used sparingly if at all. We have over 100 pieces of this pattern from a large service we recently acquired form a local estate and will be adding steadily over the next several days.
