Vintage Sewing Embroidery Themed Printing Stamps, Press Blocks, Letterpress

Set of 3 vintage letterpress/ printing press block stamps featuring different embroidery/sewing stitch illustrations, perhaps from a tutorial or educational guide. They are metal stamps mounted on wood. These could be used as rubber stamps for modern day crafts. Good vintage condition although they do show signs of wear. Please see photos for condition details as well as measurements/scale and feel free to ask with any questions. Thanks!
