This is the monument for Peter Andreas (1963-1994) in Highgate Cemetery, London. His name and dates appear at the bottom of one of the two conjoined pyramidal obelisks. No name or dates appear on the other—although it's not at all unusual for a blank "twin headstone" to be erected on a gravesite intended for two, awaiting the addition of a spouse/partner's name and dates following his or her own passing.

It's worth noting that such an unusual and imposing cemetery monument as this, standing roughly 12 feet in height, would have involved a substantial expenditure.

I'll withhold any further public commentary or observations about this monument.
