I got all the Fire/Police related U.S. stamps. A couple have already been posted, but thought a collective post would be good. I consider #1122 part of Fire, as an integral part of Forest Conservation is reducing fuel with control burns, handled by the Forestry Service and Fire Departments. Ambulances have been included as well.
If I missed any, please let me know. I know
I got all the Fire - I collect FDCs for them
