In the tour of the alphabet, Sunday stamps is up to the letter J. I have an image from the US Postal Service:

Janis Joplin lived from 1943 to 1970, dying of a drug overdose in October of 1970. She electrified audiences wherever she performed.

When I was younger I did not appreciate her singing but I do now.
Please visit Sunday Stamps and see who else has joined in this week.
