Set of 3 vintage white milk glass eggs, traditionally used as nest eggs to encourage hens to lay in a specific nesting box.  These are hand-blown, as evidenced by subtle pontil marks on the eds.  Smooth, opaque white glass with slight variations in shape, size, and finish due to the handmade process.

Era: Likely early-to-mid 20th century
No cracks; a few light surface marks from age and use (see photos)

These were inherited from my grandmother who was born in 1903.   Potentially Antique, but not positive
