Persian Leaf was a popular pattern that has the greystone glaze, the high gloss mottled glaze used successfully for Patch, (4015), Blue Peony, (4016), and Persian Rose, 4040). The same design will be reworked in earth colour lustres and enamels to become the Tarragona pattern, (5623), later in the following year.
Collectors are likely to come across examples with a variety of backstamp styles as the production period straddles the time when Crown Ducal stopped using the AGR2 style and used a variety of other stamps and transfers until the beginning of the wartime restirictions on decorated pottery in 1942.
Another observation about this design is that Charlotte clearly preferred it for creating variations. Apart from Tarragona, which which has its own number of 5623, there are three other notable versions.
