yes, definitely - except we've been here before with this exact title/poster before.
where was the lesson learned?
but if you look by date sort with HA, it's obvious they changed their opinion (without changing history aka sanitizing their site)
but look Matt - there is a simple rule: if you don't know what it is, yuo don't know what it is and need to find out exactly what it is before you say "this is what it is"
no amount of disclaimer would get the approval of anyone if it was at HA, MPB, MPE, Ebay, Christies, the British or French auction houses etc.
This really seems the simple way to deal with this or (or any) poster where there might be a question.
Either keep it from the auction block, or present it with what is known (or not), without attributing any "hard" facts about it, when those facts aren't known for sure. As was mentioned earlier - the dating/release of this poster seems hard to pin down, what with talk of later RR using the same art (as many RR Belgians have been created with). And not knowing for certain isnt a bad thing at all. Just be clear on that point -- was my point.
Ultimately, that's what caught my eye: the wording in the title vs the wording used further down in the description. And I thought it worthwhile to ask about, as we arent talking a 10 dollar poster here. Hopefully, the one man with the answers will chime in, at some point.
