does anyone know the origin of this sculpture, who made it and possibly when? If there is a better place to ask be sure to direct me
The photographer is Sara Zinelli. Found it via reverse image search where she's selling it as a stock photo on gettyimages:
Here it is on her website:
I can't really make out what the page says. You can either try to find the article online or contact her directly to ask.
Might be the same one from a less flattering angle
A basic search for Brompton Cemetery Cherubs doesn't bring up much except for the occasional picture of this sculpture without any artist attributed to it. So it probably wasn't anyone famous who sculpted it. Most likely it was just a headstone sculptor.
I think it's the same one, just different angles/lighting. It also looks like yours was taken when the statue had more dirt on it.
The centermost curls of the hair look the same, and they both have the same grouping of feathers at the center of the wing and the posture is identical.
