A super pair of mid century cufflinks by Alex Holm, Denmark. Stamped to the side of the posts with 'Ax.H 925' (925 grade Sterling silver, Alex Holm). 
Mid century era (apx 1960s) and very much in a Minimalist and Modernist style (with the simple striped/grooved rectangular flat panel shapes). The design is the same front and back. Each block shape is roughly 21mm x 7mm x 2mm - a good size that will be seen. Both have a curved hallmarked stem/post and identical back pieces; both toggle very well. They weigh 17 grams together, a good chunk of quality vintage Danish silver. 
Good condition with a few tiny signs of age. Photos don't do them justice.
