Power Prop WWII Glider - Introduction

This is my collection of Power Prop WWII Gliders which came in cardboard backed packages.  I found them all on E-bay and was really happy to have purchased them.  They appear to be the same Power Prop Gliders in the red & blue envelopes that I posted about recently as well but with better quality graphics.  I have 8 of the set of 12 (or 13?) and I hope to find the rest some day.
