I do like it when I get to see something a bit different. Academy certainly provided it this year. Of course, they had plenty of models of planes, ships etc on display, all up to their usual standards:
1/72 B-17G Flying Fortress "15th Air Force"
F-8E "VF-111 Sundowners" and F/A-18C "Chippy Ho! 2009" in 1/72
But they also had their Leonardo Da Vinci models on display too!
Spingarde & Self-Propelling Cart
Mechanical Drum & Catapult
Very cool! I approve!
