Definitely for summer vacation! This is a very practical and rather American warning sign, used to hold balls and toys for playing in parks, etc., and also serves as a sign to alert others, such as cyclists, that "children are playing," encouraging them to be careful. In America, it seems to be a tool that contributes to protecting children, even on roads within housing complexes. I have various other items for sale as well. Please take a look if you have time. #AyamocaGoodsList #AyamocaLadiesList #American #AmericanGoods #Sign #Warning #Children #PlayEquipment #Park #Yellow #SetagayaBase (a Japanese TV show) #SummerVacation #GoingOut #Outdoor
