Dear Jerry,

Thank you for your request. The presented object is a single teacup with the measurements of approximately 3 1/2 inches diameter, 1 3/4 inches high with 1 3/8 inch square base. The teacup has a blue and golden decor and is hallmarked by Bohemia Porcelain Works of Neurolau, Bohemia (Czechoslovakia). This cup was made in the first half of the 20th century.
This piece is in good condition and there are no serious damages visible.
An estimation would be between 2 to 4 USD.
This estimation is based on actual recent past recorded auction sales of comparables. Retail "asking prices" can be higher and vary.

With best regards,
Georg
