Martinex1: I am going to keep my own comments pretty sparse today, as I feel the pictured samples here speak for themselves. The annual Marvel Calendars that ran through the Bronze Age were special. Each published calendar was itself an event with thematic influence, fantastic art, and interesting tidbits.
I particularly enjoyed the 1976 Bicentennial edition with our favorite heroes clad in revolutionary garb. But no matter the year, I liked reading the daily notes, anniversaries, and bullpen blurbs. The calendars were another way that Marvel reached its customers and readership and brought them into the fold. It was FOOM, Bullpen Bulletins, and Stan's Soapbox rolled into a beautiful spiral bound once in a year package.
So here is a large smattering of examples from those days long ago. Which were your favorites? Which did you own? And did you manage to keep these nostalgic collectibles intact? (Thank you to the posters, and collectors on the world wide web for all of the various photos and making this post possible). Cheers!
