Walt Disney's Winnie The Pooh And The Honey Tree 1977 Sears Sponsor Promo
Sears Winnie-The-Pooh sponsor billboard
In 1977 when NBC aired "Winnie the Pooh and the Honey Tree", in the beginning the opening credits were edited to make room for a Christmas themed sponsor tag for Sears featuring Piglet, Owl, and Eeyore putting together a wreath with the Sears logo in the middle of it and Pooh comes in floating in an upside down umbrella.
The same case happened again the following year (in 1978) when NBC aired "Winnie the Pooh and the Blustery Day".
This was not found on any home entertainment format releases.
