The triumphal entry into Jerusalem on Palm Sunday. The palm is a sign of victory.
The letters, as placed on a board at the top of Jesus' cross, stand for the initial letters of the Latin words "Iesus Nazarenus Rex Iudaeorum", Jesus of Nazareth, King of the Jews. (John 19:19)
The cross is a symbol of Christ because of His sacrifice on it. It is also a symbol of Christianity.
The crown of thorns placed on Christís head stands for a royal diadem.
Three nails used in crucifying Christ, two for hands, one sufficing for both feet, overlapped. The crown and nails also indicate the suffering of Christ on the cross.

We saw similar designs (stained glass windows?) somewhere on the internet a very long time ago and adapted to banners.
Every year, throughout Lent, text about the symbolism is included in Sunday bulletins.
