It should be inside the drawer for a dresser, but for a table or chairs, it would be on the bottom. Not sure about headboard or trunk. Only higher end furniture was permanently marked in the 50s and 60s, and so if it was mass produced furniture, you might not find a mark at all, and it would have been labeled with a removable tag. A lot of high-end custom furniture is not marked either.
