The number of transfers available for 28mm is lovely. Go to 10mm and there is nothing but roman and some very limited Greek.
Either way it does not matter. This project is huge. Doubling the time per unit to paint can't happen if I am to ever finish.
No decals, transfers? Amazon-ed some decal paper. Then google searched Carthaginian shields. Two hours searching and resizing images and I got my decal sheet.
Cutting these little bastards out, SUCKS! It would be faster to hand paint the shields.
