You would have to be a very old JW by now to remember when the Watchtower Society INSISTED that Jesus did NOT have a beard!
Look at the older publications and you'll see illustrations of this weird teaching when Jesus is depicted.
Public talks included reference to beardless Jesus, too.
NOW HERE IS WHERE IT GETS INTERESTING.....
In the Questions from Readers May 12, 1968 Watchtower the Society collapsed and threw in the towel on the crackpot teaching of beardless Jesus.
If you carefully pay attention to the language they use IN EXPLAINING how the idea of a beardless Jesus was acquired in the first place.....
you can see they are AWARE of how flimsy it was all along! Also, you can see how dishonest they were in using such evidence to create that belief.

"It is appropriate, however, to give consideration to arguments advanced to the effect that Jesus was beardless. This idea has been largely based on theories built up by certain archaeologists with regard to the so-called "Chalice of Antioch." This is a large silver beaker or cup within a silver framework shell of vines and figures of men. On one side of the cup is a boy, with five men facing him, and on the other side a young but more mature man, beardless, with five others facing him. All appear to be seated. The cup, supposedly found by some natives in Antioch of Syria, was acclaimed as being of the second half of the first century C.E., and therefore the earliest pictorial representation of Christ.
However, an analysis of the facts now makes it evident that the figures on the cup have been identified according to the imagination of the individuals interpreting them. The boy is considered to be Jesus at the age of twelve and the other central figure is said to be Jesus, possibly after his resurrection, or, again, it may be John the Baptist. The other ten figures have been interpreted variously to be ten of the apostles; or the apostles and evangelists; or, on one side the four evangelists with James the son of Zebedee, and on the other side Peter, Saul, James, Jude and Andrew.
There are serious objections made by many archaeologists to these identifications. Really it has been guesswork, and it is impossible to say what is represented by the figures. Some even doubt the authenticity of the cup, believing that it may be a forgery."
