Interesting John Lennon Yoko Ono photo

this was sold at Copakes last weekend I think it went for $100. But interestingly the size of this one was 21x17" whereas the other known ones were 3x5". So did the photographer Kreger simply blow up one of his negatives and someone happened to obtain it? Here's the back story:

Heres the one that sold last weekend:

 

several of these, numbered by the photographer from a set of 150, have sold previously between $250 and $750. these are 13x10" I passed when last weeks auction hit 100 but probably a pretty good deal.

Here's a version that @journeymagazine found.

Here's another size on ebay, with some more info.

So I'm guessing the image sold really well for him and he made lots of sizes to fit everyone's needs?
