Not many will be throwing a leg over it, but it will still have broad appeal.
I'd hope the buyer would be one of those --- or at least willing to do it if it fit him/her. Far be it from me to criticize someone for buying a bike for "collecting purposes" that doesn't fit (as I'm certainly guilty of that), but two points:
1.) at least this isn't one of the frail, crack-tastic frames of the early/mid nineties that seem to get so much love here. There's no reason this one couldn't be ridden regularly.
2.) as someone who's had my large-sized bikes criticized here and elsewhere for not being as aesthetically pleasing as "normal" (i.e., smaller) bikes, I'm interested to see if those kinds of comments get applied in this case. While I agree that we get used to seeing bikes in a particular size range, to me if you're 6'3" plus, I'd much rather see (and ride) a bike that actually fits instead of a "normal" size frame with a stupid 20" long seat post and 8" drop to the handlebars.
