The Drexel Aikido club held a seminar there some time around 2002 or a bit earlier. Here, Craig Constantine is demonstrating a standing ikkyo finish with uke Sempai James Jackson.
Of particular interest in these photos are the belt colors. These photos are from shortly after Sensei Wirth decided to move to using colored belts for the kyu ranks. Originally, 6th through 3rd kyu wore white, while 2nd and 1st kyu wore brown. In the photos from this seminar, students from Maryland are wearing the newer-scheme red belts for 2nd kyu, while the Allentown students are still wearing the old-scheme brown for 2nd kyu.
