Wood liked to paint faces he knew well. For the grave farmer he used his dentist, a sour-looking man. For the woman standing alongside him, the artist chose his sister, Nan. He stretched the models' necks a bit, but there was no doubt who posed for the portrait. Nan later remarked that the fame she gained from American Gothic saved her from a very boring life. The Buffalo Nickel Today, American coins honor prominent figures of the US government - mostly famous former presidents. But the Buffalo nickel, produced from 1913 to 1938, honored a pair of connected tragedies from the settlement of the American frontier - the destruction of the buffalo herds and the American Indians.
伍德喜欢画他熟悉的脸。为画神色严肃的农夫，他选择了他那表情木讷的牙医，至于站在他身边的农妇，他选择了自己的姐姐南。他把模特的脖子稍稍画长了一些，但无疑能看出谁是画像的原型。 南后来说道，《美国哥特人》带给她的名誉使她摆脱了一种非常乏味的生活。 野牛镍币 今天，美国的硬币都用来纪念美国政府的杰出人物，其中大部分是著名的前总统。但1913至1938年间发行的野牛镍币，却是为了纪念由美国拓居引起的两起相互关联的悲剧──野牛群的灭绝和美洲印第安人的毁灭。
