Broderbund has a collection called ClickArt Christian Graphics Deluxe. It's a great collection of wonderful clip art, and in it's holiday section there is some good Christian Patriotic Clip art.
Caleb Project's website also has some clipart, but not very impressive. http://www.goshen.net/calebproject. In addition, I think most graphics programs that contain clipart will have maps, globe graphics, and graphics of different ethnic people.

I know that the SBC Foreign Mission Board has clip art sheets available --some of which are not denominationally specific. Besides individual agencies, The Church Art Works provides commercial clip art for the church -- some of which would be missions related. I know that they can provide clip art in books or on diskette, though I don't have an address handy right now.
There is a great clipart site at http://www.barrysclipart.com There is a section of Christian clipart, though I don't know that there is anything specifically oriented towards missions.
You might try the following address. I have found some real decent clipart, and there are several pages to link to after.....http://ns2.clever.net/~graphics/clip_art/relg/relg.html
