Here are two sources for some beautiful nativity and Christmas images that showcase the artistry of nonwestern cultures:
The first was sent to me by my friend Paul Neeley. It features fourteen creches collected by Rev. Jerry Dvorak, a pastor at St. Peter's Church in Richfield, Minnesota.
World Nativity, which I highly recommend that you check out. The website is run by the Hydes, a Mormon family who "started buying Nativity scenes from artisans in poor or developing countries as a means of helping the artisans generate income in a way that preserved their dignity... the response has been so high that we have sold thousands of Nativities from more than 100 artisans since 2005. Profits are given 100 percent to charitable causes and micro-credit projects in Third World countries that benefit the poorest people on the planet." This sounds like a WONDERFUL way to help many in need around the world, in a way that helps them become more successful business people!
The website features nativities from the Hydes' personal collection (not for sale), as well as others which are available for purchase. Some of these for sale items include Christmas ornaments as well. You can see images of others from their collection on their Facebook page.
