I am trying to sell something on Ebay for the first time.?

Nobody has bid and it has already been about 36 hours. Do people wait till the end or what. Or does my item just suck.a href="http://search.ebay.com/search/search.dll?from=R40&_trksid=m37&satitle=Comic+Images+Norman+Rockwell+collector+cards&category0=" rel="nofollow"http://search.ebay.com/search/search.dll…/a
