One handwritten note reads: “To Frank and all mail carriers, thank you for delivering our mail during this difficult time. We appreciate it very much!”
Elsewhere, a childlike drawing of a USPS vehicle adorns this message: “Thank you postal workers! Stay safe.”
The 30-second video is the 10th installment in a series.
The Postal Service released the video last week and shared it on its social media channels, where the organization also distributed the previous nine installments.
