Here's a beautiful map of Lake Champlain that I did for a customer in Vermont. This decor map is large, 6ft-4in. x 3ft-2in. and is gallery wrapped. The map is from a watercolor painting and is printed on canvas with archival inks. After printing, I come back and hand paint areas of the map to high light them, such as the birds etc...
Interestingly, I hide things in the waters. Folks love to search the waters looking for the hidden items. They are tiny, but they certainly make this map a conversational piece.
One of the neat things that make my maps special, is that you can tell what time of day it is on the map. As shown, If the shadow is on the west side of the birds, then the sun is rising. If the shadow is on the east side of the birds, then the sun is setting.
I use waterfowl that are common for the lake area, such as Canadian Geese, Great Blue Heron, Bald Eagle etc... These three Canadian Geese appear to float over the map.I try to name important area's on the lake, especially the islands, points, rivers etc... I added this sail boat to the picture because I thought it would make an interesting photo. Check the colors out of the lake.
