to Dear Taylor,
Thank you for contacting Mearto with your appraisal inquiry. Your jug is what is called a Hobbyist piece. Meaning that the person that painted the porcelain was not a professional artist associated with the factory; they purchased a "blank" from a store to paint. This was very popular in American with ladies, especially from the middle class during the first quarter of the 20th century. These pieces were typically made as gifts, or to sell in church bazaars or other types of fundraisers. One way that you can tell that your picture is a Hobbyist piece is the fact that the painting is not underglaze, meaning it did not go through the last firing process, which gives it the overall "dull" finish. Your piece was made by Delinieres & Cie, which was a factory in Limoges France. Based on the marks, it was built between 1894 and 1900 and is in good condition. It has been hand-painted in an Art Nouveau style and is signed on the base by the artist. Based on recent price valuations of pieces similar to yours, with the same level of artistic skill, a fair market value estimate would be between 45 and 75 US dollars. Please let me know if you have any further questions.
Best Regards,
Morgan
