E. Greenfield's Sons est. 1848, Fifth Avenue Building, Fifth Avenue & 23rd Street, New York. Monthly Suggestion for May - Rhubarb Jelly. The Rhubarb plant is the first of the goodies from the Kitchen Garden. It is delicious and healthful. A few Rhubarb Stalks and a dish of the chocolates (Delatour) tastefully displayed in the Retailers' window would be novel and might start a little rush. After all it is only a suggestion.
