Very vintage rose crochet doily and 50 similar items

Very vintage crochet rose doily. I don't know the age of this, but based on how it came into my possession, I believe that it is from approximately mid-50's to mid-70's. Approximately 12" diameter. It is not in the very best of condition. It needs a bit of TLC and perhaps a gentle cleaning is in order. The central doily seems to be intact, just needs to be carefully reattached to the rose and leaf border. I debated whether to repair and hand wash it or sell it as is. As you can see, here it is, as found. I'm hoping that a lover of very old things will decide to add it to their vintage crochet collection.
