My mom is looking to purchase a 6 piece set of antique wicker made by Kaltex or Michigan Seating Company. The set has a 3x4 table, sofa, 2 rockers, and 2 chairs. I cannot find anything on the net about this set and any info on a value and idea of rarity would be greatly appreciated. I have attached pics from the ad she is looking at. Ad says fabric is original and date of manufacture around 1919... any info would be greatly appreciated.
