Looking at the close up of the fabric print, I think it may be from earlier...maybe the 30s or 40s. The coarse look of the weave and the colors suggest that age to me. You could always applique a similar looking flower applique of one of the colors in the print over the torn area. Should be fairly easy to do. Don't know how sturdy the fabric is. Check and see how easily it might tear by testing a corner area. If it tears easily, I wouldn't put a lot of time into the quilting. You could do a quick all over flower quilting design either by hand or machine. My sister also has sewn an inexpensive old lace over an old fabric to hold it together if it isn't so very "sound."
