Yeah it depends how its posed and photographed but all I mean is that side-by-side with most HT heads its small (even though HT heads have reduced a bit over the last five or so years.)
The major issue I had with it is that it really doesn't work with older SSC Indy figs (which you obviously want it to) - those were back in the SSC bobblehead era and the heads are literally 30% bigger than the little TOD Indy head - some almost look like 1/4 scale Premium Format heads next to it.
I just display the TOD head in certain ways that downplay the size issue - I have one on a German Indy outfit (because I actually like it best with the hairpiece not the hat) that's on a slightly smaller SS body and it works great, and it's to the front of the display so it looks bigger vs say SSC Henry or SSC TLC Indy (which has the biggest SSC head ever made) that are further back.
You find a slightly smaller scale muscle body and it can look perfect - I'm working up my sweaty TOD bash and I found a muscle body that isn't as big as most are. And yeah, no jacket helps.
