phone number on the label (513.58.30) is a vintage 7-digit Brussels format. 
This is a stunning, authentic piece of textile history from the renowned Real Lace Manufactory (Lace Gallery), formerly located at 30 Rue du Lombard in the heart of the historic lace district in Brussels, Belgium.
This handkerchief is a true "New Old Stock" find, remaining in pristine, unused condition since it was originally purchased (approx. 1950s-1970s). It features the original blue shop label and the rare "Hand Werk / Fait Main" (Handmade) certification stickers still attached.
