The following was recounted to me by someone named Darynne Jessler about the Blunder Wacky Pack ringer shirt:
The Blunder Bread shirt is no rumor. There is a
picture of me in it - two in fact. But I don't have access to the pictures (long personal story). But I
promise you it was white with red on the collar and sleeves. I wore it all the time. I don't know where I got
it. I was like 8 years old.
The following was recounted to me by someone named "Frodis" about the Blunder Wacky Pack ringer shirt:
I am 28 years old and I still have most of the 1979-80's Wacky Package
reissue cards. ... Anyhow, my reason for writing is that I still have a
"Blunder Bread" Wacky Packages t-shirt. I got it for my birthday when I was 6 (1981). It's quite small,
with a red ring collar. So, you can definitely remove that from your "rumored to exist" section. I also
specifically remember seeing a Crust t-shirt, as well as a "Milk Muds" t-shirt at JC Penney department
store in Matteson, IL sometime in 1981.
