A few more children in difficult circumstances will be reading “Click Clack Moo: Cows That Type” and several Dr. Seuss books this Christmas, thanks to donations made by members of the Lower Manhattan Marketing Association. LOMA members donated 40 children’s books and toys to Safe Horizon (safehorizon.org), which aids families suffering from domestic violence. The gifts will be brought over to Safe Horizon’s center on Lafayette St. Thursday, the day before Christmas.
