I believe this old postcard is of the cemetery in Los Angeles
associated with the Veteran's Administration Hospital.
There's no more room in it.
Recent VA burials are minimalistic and the body is taken into another county.
So genealogically, the person might have a Los Angeles County death certificate but not a Los Angeles County burial.
If you're driving on the 405 Freeway you can see the stiff rows of identical tombstones, standing, yes, a bit like soldiers at attention.
As far as I know the Soldier's home is abandoned but on the property. Since there are so many homeless veterans in the area, there's talk of tearing it down - who needs another historical site when modern housing is needed?
