Well you can: find your own pot of gold that is! In the webstore of Warlord Games. There in the Non-historical section they have this very nice Leprechaun, called Marty McGuinness. I have a friend and co-worker who's terribly fond of Ireland, has worked for Guinness while studying in Dublin and who's family name translates into Brewers in English so what better present to give him, for his birthday then this mini? Oh I guess a huge collection of speciality beers would be better but there's no fun in there for me now is there?
So without further ado here are some pictures of my version of Marty McBrewers!
The figure itself is pretty nicely detailed, there's even a small shamrock on his coat. Yet this complicates painting a lot since you'll need at least 3 different shades of green: coat, pants and shamrock. For his hair and beard I chose orange, because I wanted a spot-colour to contrast with all the green. The pot of gold is attached to the figure itself but to make the base more interesting I added a small beer-stein and a barrel of ale.
In short: a very nice little model deserving your painting attention if ever you fancy something non-historical!
