How do we identify modern monuments which have been erected as a memorial to a well known and revered individual.

Am prompted to ask this question by the recent entry below the photo of a modern rock art carving:

I've debated if it's a good idea to put this photo here, but have decided it must be done. It's under tma's 'artistic/interpretative' section, as it is a photo of a modern carving in the CnR style. In case anyone finds this new CnR motif carved on the outcrops at Blawearie, just across from Old Bewick, please don't mistake it for the real deal. It's a modern carving, created in 2012 to act as a memorial for the mighty Jan Brouwer (rockartuk), creator of the now sadly unavailable British Rock Art Collection online database. Apologies to the rocks, the archaeological record and all, but Jan contributed a heck of a lot of time and effort to the study of these carvings, and it seems fitting he should be accorded this tribute.

I can think of quite a few modern 'ancient' monuments - a standing sarsen stone up near Barbury Castle as a monument to Richard Jefferies and Alfred Williams (a plaque attached with some lines of poetry by each). A sarsen stone circle in a park in Wantage as a memorial to John Betjeman. I love the carving in memory to Jan Brouwer and think it fitting. My only concern is how are people informed of its origin - a plaque wouldn't be in the spirit of the setting.

No offence to anyone intended by this post - a genuine question of interest/concern.
