Now, this is serious... Many collectors will give their high teeth for one of these.
I don't want to add to the stress you are facing in relation to your husband's illness, but, if you really want to sell this - and in as little as 3 days - you will need to post more and better pictures and provide more information - from the pic posted it looks in remarkably good condition with no ring wear, can you take it out of the plastic cover and take more pics - both front and rear? What is the back story behind this record - where did your husband get the record from, and when?
