There is no undisputed historical depiction of Jesus.
The most common illustration are Christian icons. Images flourished in Medieval art. Most surviving images of Jesus have in common a number of appearance traits which are now almost universally associated with Jesus despite lack of evidence for the accuracy of these depictions.
No detailed physical description of Jesus is contained in any of the canonical Gospels. During the Roman Empire's persecution of Christians, Christian art was necessarily furtive and ambiguous. The earliest surviving Christian art comes from the late 3rd and early 4th centuries on the walls of Christian tombs in the catacombs. Here, and only here, Jesus is portrayed in two different ways: older, bearded and robed and another as a bare faced youth holding a wand. He uses the wand to change water to wine, multiply the bread and fishes, and raise Lazarus. When pictured healing, he only lays on hands. The wand is thought to be a symbol of power. The bare faced youth with the wand may indicate that the Jesus was thought of as a user of magic or a wonder worker by some Early Christians.
There is also the Shroud of Turin, which appears in history in 1353 and which some have speculated is the same image as the Mandylion of Edessa, which disappeared in the wars surrounding the fall of the Byzantine Empire shortly before then. Controversy still surrounds the claims made for the Shroud of Turin.
There are also icon compositions of Jesus and Mary that are traditionally believed by many Orthodox to have originated in paintings by Luke the Evangelist.

Several Hadith quote Muhammad describing Isa (the Islamic name of Jesus) as he appeared in a dream, and during Muhammad's ascension to Heaven:
"While I was sleeping, I saw myself (in a dream), performing Tawaf (circumambulation of the House of God in Makkah). I saw a reddish-white man with lank hair, with water dripping from his head, I asked, "Who is this?" They replied, "The Son of Maryam (Mary)..." (Bukhari, Muslim)
"Narrated Abdullah: The Prophet mentioned...While sleeping near the Ka'ba last night, I saw in my dream a man of brown color the best one can see amongst brown color and his hair was long that it fell between his shoulders. His hair was lank and water was dribbling from his head and he was placing his hands on the shoulders of two men while circumambulating the Kaba. I asked, 'Who is this?' They replied, 'This is Jesus, son of Mary.'" (Bukhari 4:55:649)
"Narrated Salim from his father: No, By Allah, the Prophet did not tell that Jesus was of red complexion but said, "While I was asleep circumambulating the Ka'ba (in my dream), suddenly I saw a man of brown complexion and lank hair walking between two men, and water was dropping from his head. I asked, 'Who is this?' The people said, 'He is the son of Mary.'" (Bukhari 4:55:650)
"Narrated Abu Huraira: Allah's Apostle said, "On the night of my Ascension to Heaven...I saw Jesus who was of average height with red face as if he had just come out of a bathroom." (Bukhari 4:55:607)
