Bird bath top comes off for moving. The weathered concrete shows age we would guess dates it to the 1940s or 1950s. Beautiful vintage concrete garden ornaments get strong and stronger with age, as long as they sit on an impervious base (like a large flagstone or bluestone slab) as opposed to directly on soil or mulch, where they can wick up moisture and suffer freeze thaw damage.
This bird bath is currently fitted with a round tempered glass top as we use it indoors currently. The items under and on top of the glass are not included. Just the three pieces: base, bowl and glass top.
