The left hand head of the line-up looks like either Marcus Aurelius or Lucius Verus and I think one of the others is Vespasian (the one on the right). One of the middle ones may be Trajan but the light angle is wrong to be certain!
It's a lovely figure (and Laruccia has got the way the toga is tied absolutely correct, including the 'bulla' - the fold of cloth pulled through at waist level). Note, also, that the figure has the correct (and special) pattern of shoe worn by this group. The only thing is I find it difficult to imagine where such a figure would fit into a collection of Roman military subjects. It could be used as a 'prop' with one of the other figures (e.g. the ones of either Hadrian - from Romeo - or Germanicus). Whatever, it's a nice figure.
I see that AL is continuing with the 'late Roman Empire' period with the other figure. This period (4th-6th centuries AD) has been little covered by other manufacturers. As usual, the helmet (a ridge, Berkasovo type) is rendered masterfully.
