These securities were issued for a period of several years, usually 10 or 15 years, and during this period investors received annual interest equal to 7% of the nominal value of the security. BTPs at 7 per cent thus represented an attractive opportunity for investors seeking fixed and safe yields.
As for the depiction on the cover of the bonds, according to your description, it seems that there was a rural image. The images used on the covers of BTPs can vary depending on the issue and the period in which they were issued. Usually the images chosen represent emblematic scenes of Italy, such as landscapes, monuments or cultural aspects of the country.
As for the denominations of the 7% BTPs, they were available in different denominations, ranging from 50,000 to 500,000 Italian lire (before the introduction of the euro as currency). The colouring of the bonds may vary from issue to issue, but they were usually characterised by shades of green, blue or red.
It is important to note that the information provided refers to 7 per cent BTPs issued under Law No. 24 of 23 February 1974 and the Ministerial Decree of 20 March 1974, and that current information on BTPs may be different due to changes in financial policies and regulations.
