Does the article say this? I don't see it.
Also, wasn't this monstrance just recently been made known to the public? If so, isn't it possible that someone who could recognize it just hasn't seen it yet?
“Does the article say this? I don’t see it.”
No, you don’t.
“Also, wasn’t this monstrance just recently been made known to the public?”
No, not really, but that wouldn’t be the point anyway. Clergy would recognize it more readily than lay people anyway.
“If so, isn’t it possible that someone who could recognize it just hasn’t seen it yet?”
Yes, but most likely it hasn’t been recognized because it is old.
