A total of 7 cards. It appears that 6 are from broadcasting or publishing companies of the time. 1950's. These are from the estate of a well known award winning industrial designer who likely worked or consulted for all of the corporations.
The card with the "Hand" art notes that it was by Suzuki Hidetaro but might also be from a broadcasting company as we did only limited translations.
Cards are overall very good with some little edge wear mostly. They are all sent cards.
