Corona di Mario Diaz

Order for Corona di Mario Diaz.

Corona di Mario Diaz was an Italian company based in Milan, active from the mid-thirties. Unfortunately it is not known an exact date for the founding of the company, not to be confused with the same name "Corona" American and English brands. The company was active (at least by some registered trademarks) in the field of mechanical adding machines, but the only registered trademark pertaining to pens is CIP (Reg. Gen. N. 116011). It is unclear whether there is any relationship with the Corona (Reg. Gen. N. 90853) trademark registered by Luigi Vigorelli in 1945. The production, as evidenced by the order of 1952 shown in the figure at the side, went even after the war, but again it is not known until when the activity has continued.

A Corona from '30/'40.

Non è chiaro se ci sia una qualche relazione con il marchio Corona (Reg. Gen. N. 90853) registrato da Luigi Vigorelli nel 1945. La produzione, come testimoniato dall'ordine del 1952 riportato in figura a lato proseguì anche nel dopoguerra, ma di nuovo non è noto fin quando si è protratta la attività.

The company produced good quality celluloid pens, featuring a Corona marked gold nib, with the brand name imprinted on the body, between two circles, in nineteenth-century characters. It's quite interesting, at least in the case of the sample in the figure, the decoration with rings alongside the inscription itself.
