Hi Marty! welcome to basenotes! and boy, what a way to start a thread, Profumum Olibanum!!
No, Olibanum is nothing like Avignon. instead, Olibanum feels very juicy green with the smell of freshly crushed, tender, juicy stems with hints of woody notes held together firmly by a glowing note of orange blossom and a lovely note of incense(quality as good as XXV, if not better) on a base of woody notes...it's a pretty strong incense based scent yet, not like avignon(which is a frankincense dominated scent with totalyl different approach)...this one's more on the LV Incensi side when it comes to Incense.
it's quite potent and has (like all profumums) a smoky sillage
