Pbase has some great images by many fantastic photographers, but that's not all.
Quite a few show more than pictures and EXIF info. They display their friendship in facilitating with their knowledge and often with spontaneous feedback, as was in my case.
Credit for the next four pictures goes to Enny Jameson,( http://www.pbase.com/moensja/profile ) who responded so gracious to my ancestor image in this gallery. http://www.pbase.com/bernard74/image/67198126
