When is this SEMA pamphlet from?

This came in a set of vintage vw headers I bought for my buggy. I thought y'all might appreciate this. 

The question now is, what time frame is this from?

And now the inside 

Funny how similar that is to NRA and AARP appeals for support.

My boss is thinking that this is from the late 70's from the condition of the box that the headers were in. 

seems kinda strange in retrospect that SEMA felt that car owners rights were in danger way back then, but then again it seems like our lifestyle is in danger now too.

based on the cartoon, I'd say 70s too

Propaganda is the core growth method for many organizations.  Sowing fear is a fundamental tenet of propaganda, which transcends both time and subject matter.

Any fine print in the corners?  Lots of literature uses a code of some sort to identify the time it was made.
