I believe you mean OT.
The question is what does your word "found" mean?
All sorts of antitypes are present in the Old Testament ... scores of them ... and even before the Old Testament ... in the very first books of the Bible even Genesis.
So "found?" yes. But undiscovered because God had not revealed them.
That is what is called in Scriptural parlance "a mystery". Hid in God is another term.
You and I see Jesus all over Isaih 53. But the Jews seemed to have missed the fact ... they even crucified their King.
Here is a very good quote to consider by C.I Scofield ... a favourite of mine.

Not so, Tychicum.
Because some did not believe that did not negate the promises of God nor make them of no effect. The law and the prophets testified to Jesus Christ, which testimony is the "spirit" of prophecy -as the angel told John: and
Abraham the prophet absolutely saw the complete plan of salvation in the "only begotten" human being Son of God's death, as the Lamb of God, and our substitute", when he was given the complete living oracle of that day which the LORD has made from the foundation of the world to act out as a living prophecy;
and Jesus said Abraham rejoiced in His "Day" which he saw -the Day the LORD has made for our salvation, when our God became our acceptable sacrifice to make an end of sin by being bound to the altar [the cross] and was the "Gate to the City through which the righteous enter in".
The City of God has been understood from the beginning, having been shown to the prophets [as the author of Hebrews said, for they sought that City which has foundations, which they saw "afar off, and the Way was made known to the prophets; nevertheless, they had to wait, for the appointed time was not yet, when sin was to be made an end of and the death in spirit was to end for "whosoever will" of Adam's race. So not all believed, but some did.
Abraham "saw the Day of the Lamb of God" -the only begotten, and he named the Mount Moriah on which Jerusalem sits "YHWH SEEN"; for there YHWH [shall be] seen as the only begotten Son of the Living God, as the Lamb who removes the transgression of Adam.
-and the Psalmist understood it and wrote of it in Psalm 118, a clear picture of what David understood from the time Nathan came to him and told him "God will build 'you' a house", and David was awed and sat before the LORD in amazement at the Gospel of redemption which he was 'shown'.
-and the Hidden in God Son of Man who was to come in flesh whose name was secret -which name the fallen angels desired to look into- is the mystery revealed; though He was to come, He was not come in flesh of the second Man creation until the incarnation -and He is coming again and we who love Him long for His appearing. And "that" is what Paul saw; which is the same which Peter, John, and each and every 'elect' one "sees" who is born again in His New Man Spirit.
"That which hath been from the beginning, which our hands have handled and our eyes have seen" ,
is the testimony John gives us of that One who was "in the beginning with God and who was God", and which is "the Mystery of godliness now revealed".
1Jo 1:1¶
That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, of the Word of life;1Jo 1:2
(For the life was manifested, and we have seen [it], and bear witness, and shew unto you that eternal life, which was with the Father, and was manifested unto us
1Jo 1:3
That which we have seen and heard declare we unto you, that ye also may have fellowship with us: and truly our fellowship [is] with the Father, and with his Son Jesus Christ.
1Jo 2:13 I write unto you, fathers, because
ye have known him [that is] from the beginning. I write unto you, young men, because ye have overcome
the wicked one. I write unto you, little children, because ye have known
the Father.
1Jo 2:14 I have written unto you, fathers,
because ye have known him [that is] from the beginning. I have written unto you, young men, because ye are strong, and
the word of God abideth in you, and ye have overcome
the wicked one.
