{{Infobox_Brand|Olo}}</noinclude>The [[Olo]] began as a sub-brand of [[Aurora]] in [[1929]], more or less simultaneously with the ''sister'' [[ASCO]] and with the release of [[Duplex]] celluloid model. The [[Olo]] brand appears to have been created to address the the medium and low segment of the fountain pen market, to complement the production of first tier models marked [[Aurora]] with lower price (and obviously less valuable) but always of good quality fountain pens. But the trademark was actually recorded  ({{Marchio|41031}}) in [[1929]] for something totally different: ''milk, tea, coffee and surrogates, edible oils and fats, ..., lace, embroidery , felt, paper, paperboard, paper for upholstery, etc.''.
