You would be surprised at how staging an item helps sell it !! On something like this frame,, add something,, print or mirror,, even a calendar pic works if its the right era,, then drape around some lace remnants around a table of same vintage or close,, stand the frame against the wall,, set a couple of items around it,, glassware, figurines and I used to add a long stem red or white rose laying across the table (silk,, not real) then take your pic !! The first pic people see has to grab attention and give ideas to how they could use the item in their home !! The rose always gets a ladies attention !!
If you have other items to sell from that era,, sell them as a grouping !! Buyer has less shopping to do !! It works !! Add a romantic description !! This is what I mean when I tell people to know your market and play to that demographic !!
