I just found this tidbit of information regarding the tartan neckerchief.
"Originally then entire neckerchief was the wool Maclaren tartan. Within 2 years they just used a small square of the tartan on each neckerchief to save money."
If anyone knows where a person can buy one of these please let us know. I originally wanted one just because I thought it was nicer looking than the "pink/beige" neckerchief but now that I know that it was the original neckerchief worn, that puts a whole new spin on it!
