Vinyl Record sale Saturday

I saw my listing in the Bulletin Board; that was a new "venue" for getting the word out. I am gathering a few websites related to vinyl records to have around, in case the conversation turns that way, Saturday. Several people have called with inquiries so they must be seeing the announcements some place. I need a piece of poster board - about the extent of my creative artwork will be a poster announcement the "cause" of the record sale.
