This hasn’t happened to me in quite a while, at least in more modern (post 1965) TMR issues. 1967 was the 40th Anniversary of TMR. It was also my first year at Camp (Nainque to be precise). I don’t remember this neckerchief, but I wasn’t collecting patches back than and did not even buy a patch from camp that year.
I have not seen this neckerchief in 30+ years of active collecting TMR issues and 35+ years of accumulating TMR issues.
