I don't have any flats or long boxes, but I think I have a crapload of poster used for the same promo purposes.I've looked at completed sales for some idea of their value, but I won't be selling any time soon. Not really looking to add to the collection either. Just thought I'd let AK see another facet of music retail that they may not be familiar with, or had forgotten.
I remember when we got our first delivery of cds in long boxes. They filled 2 rows of LP bins and literally sat there unbought for several months. At that time there were few cd players and they were expensive.
