This prompts me to ask once again..no, plead once again..whether anyone can
come up with a source for plain old garden variety 16-inch sleeves. Not acid
free, not fold-over, not 6pt card..just paper 16" sleeves, with a large label
hole, for the gazillions of vinyl transcriptions many of us have in tattered
sleeves or no sleeves at all. I'd take a couple of thousand today if they were
25 cents apiece and I'm sure there are enough of us who could make up a large
order.
