I have seen two different kinds, both from Central Hobby. One is a 40 piece Children’s Sunday Puzzle (こどもスンデーパズル)with 40 pieces showing the Class Mates having lunch. I cannot make out the date on it. The others are listed as Play Goods Bonuses (プレイグッズおまけ付)with 48 pieces each for ¥250. Those are from 1986.

I’m not sure what these are but they seem to have been included with the Play Goods puzzles.
