Shall I or shan't I?

I have been looking all over the house for vintage items that I don't particularly need or want anymore with a view to having a little vintage sale with our exhibition on December 1st. The trouble is - I don't really want to get rid of anything! But I know it makes sense :-(
This is my beautiful old sunbeam mixer that I don't really want to say goodbye to but it's been hidden away for a couple of years so....... do I really want it?
