Does anyone have any experience with the 1933-34 National Chicle Sky Birds series? It's from the same company that issued the famous 1933 football set that features Knute Rockne. I really enjoy vintage cards and I would be interested in collecting a pre-war set at some point. Down the road, I intend on working on a 1933 DeLong baseball set (I just love the design)...but a classic non-sport set would be an interesting switch. I love aviation, and these cards issued in the early days of aviation. They are almost a time capsule to that era that shows how aviation was viewed by the public. I think it would be really neat. Information has been somewhat hard to come by with this set. Beckett lists nothing about it and google searching has provided limited results. This is by far the best site I have found: http://www.skytamer.com/R136.html I'd be curious to know if anyone here has any experience with this set and if so...any information you could provide would be really helpful.
