A beautifully designed and drawn stamp sent to my mother Christa by her brother Heye Paul. Looks like the postmark says "Vikingstad," which is the small town near Linköping where Heye and his wife Maria used to live (in Rappestad). I can't quite make out the date. It looks like 10. 9. 73? (September 10, 1973?) You can see more Swedish stamps from Heye here.
