I think the seller may well have been correct. Massive displays of ornaments on graves are not common where I live, (Scotland), but my OH is from Eire, and we've been to the graveyard in his home town on many (sad) occassions.
There are several graves of travellers there, they are decorated and ornamented and full of sculptures and pots of flowers, and garlands of flowers - and cherubs and angels and sets of praying hands sticking up out from the ground, there are those plastic balls full of water and plastic flowers, there are ornamented bottles of holy water everywhere. You can tell a traveller's grave from all the others - they are decorated up like beacons, standing several feet above all the others, and all spread out too.
I have learned what a lot of very strange things are, from looking at those graves.

This would be quite at home there, especially with a bouquet of (plastic) flowers in it.
