What can you see in the poster ? How many envelopes can you see in the picture

I see in the picture a post office. The postman takes mail correspondence at the post office and goes to deliver the mail. He is dressed in a beautiful blue uniform. The postman has beautiful shoes. He has a beautiful cap. Many envelopes can be seen in the picture. These postal envelopes are addressed to the people. I see large and small envelopes. These envelopes are shown in a picture of different colors. I see that the postman hurries to spread the envelopes in the picture. I see that the postman\'s work is interesting.
