This is the list of emblems available to be placed on U.S. government headstones/markers:http://www.cem.va.gov/hmm/emblems.asp
I am astounded at the variety. In spite of a lot of the negativity one may occasionally and justifiably feel about our republic, I take this as a positive sign of our diversity. (Although #98 not being shown because of "copyrights" is a bit troubling.)
Personally, I'm thinking of converting to the United Moravian Church, simply because I think their emblem (#27) is teh coolest.
