Handmade Antique Lace and Drawn-Thread Handkerchief

this belonged to my great grandmother. one of a kind, beautiful antique handkerchief. Fine, soft linen. Hand-drawn thread detailing technique. The lace surrounding the linen was hand-made and then sewn around the border in one continuous piece approx 1.75" wide. 13" square I've searched online for comparable pieces to get an idea of its worth, and haven't seen anything on the market nearly as beautiful, well-made, and excellent condition. May be gently hand washed. This would make a unique bridal or baptism gift.
