I believe photographs of the Stickle quilt are extremely limited and close-ups not permitted at all. Whether this is by request of Brenda Papadakis to protect her huge financial interest in the Dear Jane phenomen she started, I do not know. I'm sure it is also for archival purposes.
I'm sorry you feel the poster was a waste of money. I did find one document that lists the instances of the quilt in print.
