These are professional baseball cards issued by Calbee from 1976 to 1979.

Mitchell, Outfielder ③ 1979 3 cards No. No. Masaru Tomita, Outfielder 1 card Naoki Takahashi, Pitcher 2 cards Regarding condition, I believe they are in good condition as I have kept them in a sleeved file since I obtained them. There may be some initial defects from the time of production or damage from before I acquired them. These are retro cards from about 50 years ago, so some age-related deterioration is expected. Please refrain from bidding if you are overly concerned about the condition.
