From the 1980's, I think. (no date on pattern)
Do you know where I can get this pattern?TIA
This is shown in two different books and leaflets under two different names.
In "Weekend Afghans" by Sterling Publishing, circa 1987 by Jean Leinhauser and Rita Weiss, it is called "Corn on the Cob".
It then appears in a Leisure Arts Leaflet by Rita Weiss, circa 2004, "Crochet Afghans by the Pound" and it is named "Fabulous Fans".
The only difference I can see in the two publications, is that the amount of yarn required and the colors and the size the afghan should be are different. Otherwise, the instructions seem to be the same.
Hope this helps.
A quick search brought this pattern up at several sites. Here's one: http://www.acmoore.com/forum/yaf_postst2208_Corn-on-the-Cob-Afghan-Pattern.aspx
