I have posted photos of not only the stele of Dexileos but also the find spot and original position - it is however, even so, possible to find more traces of this young man. Here's the official grave monument where he was honoured after his death in the service of Athens (which marked his true grave, the tomb set up by the family was a cenotaph).
The upper element of the monument.
Detail of the inscription, notice ΔΕΞΙΛ[Ε]ΩΣ, the young man's name. There are, of course, other parts of the inscription that confirm that the two relate to the same person.
