It's Fun Raising a Family was a paperback original published in 1955. In addition to a Collins edition there are two branded editions - both for companies that have disappeared.
The edition for Montreal based department store chain Steinberg's (1917-1992) was published half-way through its life. Tamblyn (1904-1978) was a Toronto based drug store chain.
