Back in the 1950's greeting card companies ran ads in magazines seeking people to sell their boxed greeting cards. I replied to 3 of those ads when I was about 12 (without my mother's knowledge of course). They were the Columbia Card Company, the Cardinal Card Company, and the Wallace Brown Card Company. I was so excited when the mailman delivered the first box. Mother wasn't so excited though, and she was even more unhappy when the second and third boxes arrived.
I sold enough to pay for all the sample boxes and make a little profit, thanks to my grandmother, aunts, and some of Mother's friends. They were beautiful cards though, and since we got to keep the sample boxes Mother had a supply of cards for a long time. But I didn't even think about ordering anything else without asking her if it was okay!
