Unspecified book of alphabets

Unidentified publication in supplied wraps with repaired tears throughout the volume. Originally found in Portugal, estimated to be ca. 1920-40s. 28 pages of monogram letters and designs for embroidery. A few full names include Siri, Greta, Rut, Hedvig. A charming little mystery reflecting the wide proliferation of cheaply produced alphabet books for monogramming and needlework in the first part of the twentieth century.
