Wassily chair date or manufacturer, any ideas?  

Additional pictures....

That looks more like a block of text printed out and glued on by a dealer who is hoping to get the highest price possible for a copy of a high end chair. The way the paper is trimmed away after the last line at the bottom should clinch it if the wording wasn't enough.

Oh they're definitely copies, I'm just trying to see if anyone has seen anything like this that may point to origin or date! Sometimes I see something that I've seen before and I can have a lightbulb moment. Their construction alone assures me that they are reproductions.

Yes, I get that you know they are copies, I'm just saying that the label looks to me like something an individual dealer (as opposed to a manufacturer or distributor) put there to bolster the value of the chairs. And if that's the case, then the chance of finding the same label other Wassily knockoffs is very slim---and that leading to finding the date and manufacturer even slimmer still.
