There are many fabrics around a lot older than 30 years old , it is still possible to come across fabrics from the 30's& 40's ( that's like 80+ years it does depend on lots of things, I would be leery about fabrics I couldn't touch, look at. Remember too, fabrics now are not the same as fabrics then, they may be thinner, looser weaves, narrower widths... Check the return policies, ask questions, maybe take a chance, If you love the fabric and feel the price is right
