The picture below was taken in the summer of 1986 at IHS. It was the group of us who were there as grad students that summer along with IHS staff. Some help identifying everyone would be great! I'll have an even larger picture from 1987 coming down the road.

Top row: Steve Horwitz, t1, t2, t3, Dave Prychitko, Pete Boettke

Middle row: m1, Ralph Raico, Leonard Liggio, Walter Grinder, Emilio Pacheco

Bottom row: b1, b2, b3

If you can fill in the blanks, please put the info in the comments by putting name to the identifying space (e.g:"t1 = Adam Smith"). Thanks! (I've cross-posted this to The Austrian Economists as well.)
