Warlord Games have released a 28mm resin Roman General with Warhound.
From their announcement:
An absolute must for any Roman player (and for anyone fancying a challenge on the painting front) is this resin sculpt of a Roman General and his trusty warhound. We simply had to have it cast in resin to maintain such a fine level of detail – as detailed a 28mm miniature as you’re likely to see.
This model is so wonderfully grand we just had to produce him resin. We will, in the future, make the model in metal but for those who want the model in all it’s detailed glory here’s your chance.
