For those interested, while the amount of Sanford and Son collectables released are not as great as All in the Family, there are a few items that were put out, while the show was airing.
Highly recommended: Sanford and Son book, this book is similar to a photo novel, in that they photo novelize scenes from early episodes, such as Happy Birthday Pop, accompanied by balloon dialogue; the pictures are in black and white. The Sanford and Son LP record album, this record, similar to the All in the Family two lps, contains dialogue from some of the early episodes, and there is a Sanford and Son shopping bag.
Does anyone know of any other items released while the show was airing?
