It was the flag bearer for the 41C series (actually the only one) until January of 1981, when the HP-41CV was introduced. After that date, HP promotional materials used images of both the -41C and -41CV, and would likely use the -41CV if just one image was used. So, this is likely from July of 1979 to December of 1980.

Thanks, Dan. I expect you are probably correct. They could have put CV on it instead of C if they wanted to (there is enough space.) In fact, it might even have coincided with the release of the 41C.

The back pack also has PROFESSIONAL CALCULATORS printed below the picture of the 41C. How times have changed.
