The item pictured is an Antique Servants' Bell Indicator Box, which was once used in large homes or hotels to indicate which room a servant is invited to. Number of Windows: Smaller boards with fewer windows (like yours, which has 5 windows) are easier to hang as a decorative ornament, which may make them popular. Condition of Wood and Glass: The wood frame appears to be in good condition, but there are signs of natural wear and tear.
