Personally, I think we should do it now. 1 Start the publicity. Because it takes time for you to do it now, and it will take several days to send it, print it and send it back. After the holiday, the printing house will be very busy. It's best to do it well in advance, and the price increase will not be too high then.

It is now the date of 165438+ 10/0. Now you have to make the electronic file of the poster and send it out for printing!
