This was in with the letters ... wonder how old this is? I feel like I remember my grandfather using it to make popcorn ...
The Round Robin letters were from 1938 to 1982, written by my grandfather and grandmother (Howard and Dessie White) to my grandfather's siblings. The way it worked was that my grandfather & grandmother would write a letter to everyone else and put it in an envelope and send it to the next person on the list. The second recipient would add their letter and mail both letters to the next one, until everyone had a letter in the package and it would come back to the first writer, who would remove their letter and replace it with a new one. There were several rounds of letters each year (I only have the ones written by my grandparents though. makes me wonder about the other ones). Most big family events were covered, births, deaths, marriages, etc.
There was also correspondence between my grandparents and some letters from my mother, aunt and uncle to my grandparents. Fun! The following is a letter from my great grandmother, to my grandmother on the birth of my sister.
So I can now check off #5 on my list!
