At what point was knowledge about the Wagner mainstream? Obviously it was known to enough people to garner a very high book value even in 1939, but at what point did accidentally selling or trading copies in a lot stop happening? Certainly even if one had heard about it, most had probably never seen one, or even a picture of one. It would not surprise me if a Doyle still trades today in lots with both sides unknowing of the rarity.
