Quoted from flynnibus:And never mind they are less and less a unique piece (even if everyone is different) when they become common place because hundreds or thousands of drawings are sold.
They were unique talking pieces when they were things that normally wouldn't be in the public's hands.. because they were internal to the factories. The fact it was outside that process kind of made it so interesting.. even if the subject matter itself wasn't all that fascinating. Now, that will be diminished because similar drawings will be so common in the open market.
The original art and concept stuff is a bit more interesting because it has real creative aspects and uniqueness. The mechanical assembly drawings are less so IMO.. and the 'rarity' (if you even want to call it that) of having such drawings goes down by the day.
When I was at Gene's before the Rick took everything, that I saw actual pallets full of this stuff. We are talking about drawings measured in pounds of paper.
Book after book after book all sloppily stacked up with all these old drawings. Neat to look at but far from anything collectible.
