I found this in a box of stuff left to me by my mom. She grew up in a carnival & I think this poster/flyer was a internal (for carnival & fairground owners and workers) piece mailed or given to workers? I understand the thanking the fairgrounds they played at, but why so much on being a good citizen? Maybe this was from during the cold war & it was a civic duty thing? Any other ideas? - I'd really like to know what this was! Thanks!
