San Francisco Mayor London Breed, along with former mayor Willie Brown were on hand to collect toys.
A survey by the U.S. Census Bureau estimates more than 12,000 children under 18 are living below the poverty level in San Francisco, and the toys are going to those who need them most.
Lefty's hopes to exceed their 2016 record of collecting 10,000 toys in a single day.
The drive was being held at 145 Jefferson Street.
