I am not going to use pictures like that. A few guidelines to choose the pictures :
1) should represent population with a
high frequency of the haplogroup, if possible
prehistoric rather than modern as most modern populations are heavily mixed, and modern Y-haplogroups may hide former lineages (as I explained for R1b in Western Europe, but it is also surely the case for J1, since polygamy was and is still very widespread among J1 societies).
2) give preference
objects or buildings made by the ancient people of the haplogroup, ideally authentic ancient objects
showing what ancient people looked like (as I did for
E1b1b and
J2).
3) pictures must be reasonably beautiful and not copyrighted (or available for purchase).
Caucasian J1 is pretty much limited to the Kubachis, Kaitaks, Dargins and Avars. However, as these people still practice polygamy (or at least gave it up recently), their high percentage of J1 might be fairly recent. As these are very small and isolated populations, it is possible that a few dominant male lineages replaced most of the other lineages within the last 1000 years only. In that case, Caucasian J1 may have little to do with the original autosomal J1 ancestor from which they descend. Until ancient DNA proves that J1 was indeed a common lineage in these populations since ancient times (Neolithic, Bronze Age or Iron Age), I would rather refrain from even thinking of them as quintessentially J1 populations.
