Here's the Character-Culture-Citizenship Guides 7 - Keep well.
Most people say the copyright is 1936, I think because that the year that was quoted for the posters on the Antiques Roadshow. But there are actually multiple copyright dates on the Character-Culture-Citizenship Guides, from 1932 to 1939 - and maybe even into the '40s.
The copyright can be seen pretty easily on most posters, right under the "Character-Culture-Citizenship Guides" title. I've seen 1932, 1936, 1937, 1938 and 1939. It's not out of the question that the posters were printed every year since they were teaching tools, but the above years are the only ones I've actually seen.
There are also Character-Culture-Citizenship Guides without a copyright date on them. I believe these were printed after the dated versions (for reasons I'll go into when we get to number 13), so into the '40s. I've heard that they were printed till 1943, but without dates on the posters to verify, it's hard to say for sure.
