World Pentax Day was held during the weekend of February 23-24, 2013. As it happened I took my girls to see the WRAM Show that weekend.
You can see my submissions to World Pentax Day here and here.
This is a model of an Aeronca C-3, with a model of the model under its wing, complete with a modeler holding a miniature R/C transmitter. It was taken with my Pentax K-5 and Pentax 35mm Macro lens.
Unfortunately I wasn't bright enough to note who the clever modeler was.
