This seller, a frequent lister in this category, made an error in offering this rare and desirable tri-fold invitation for a paltry BIN of $28. This first appeared in Dennison's 1922 Bogie Book with a stock number of H82. The artwork and lettering are compelling. The fact that it was unused is a nice bonus. These typically change hands for $85 or more. I sure hope she lists another one for $28!
09/19 Update: An identical one from another seller sold on 09/18 for $192.39!
