Hello and thank you for your question!
The three chairs shown in the image are classic in their style and construction. They would indeed appear to date to the period mentioned and look to be in very good/ excellent, well-preserved condition - the key characteristic, in this instance, to relative value. As such/ as seen, and assuming the chairs are in the condition they appear to be in all around, each would have an estimated fair market value in the range of $125-$175 (FYI, full retail in a nice shop might be more in the $200-$250 range each.)
That said, were you so inclined, updating the fabric would do much to bump up the asking price on these. Although the integrity of the chairs is squarely in their age, style, and, again, their condition, the current fabric dampens their otherwisel great curb appeal. With new on-trend fabric, the asking price for these at fair market could be seen more at the upper end of the range above and maybe even a little more ($200-$250 each). Full retail would then be more like $300-$350.
Again, a nice trio of vintage wicker chairs in what appear to be very good condition which, with a bit of effort, could recognize even more of their potential.
The best of luck with them and thank you for writing in!
