The sketches and photos that are in this calendar are only a few of the original sketches and photos from posing sessions that were saved in 1979. The true beauty of these sketches is how they have aged. We've made no attempt to remove the stains or whiten the yellowed tape. We have of course lightened them overall from the actual sketches so you can use your calendar. Some of the actual sketches in this calendar have been digitally reworked for a designed effect. There is a running text throughout this calendar that is a short biographical look into Greg and Tim Hildebrandt's life. Each page also includes quotes from the Hildebrandt Brothers.
