Flickr Album Corrections

I discovered that the negatives in the envelope labeled 1986 RiverCon were actually from the 1987 RiverCon. My Flickr album for 1986 RiverCon has been deleted and the images from there and from the negatives actually in the 1987 folder are now in:

Now I have a double mystery. I have no photo albums or negatives for the RiverCons of 1985 or 1986 (I bought my first 35mm SLR in 1984).
