The dynamisation of art in the 20th century and its impact on typographie. by Michael Mahla. As early as the first decades of this century, velocity, machines and films were well-known phenomena. They had a decisive impact on the artists of those days. The introduction of new technologies transcended imagination, changed communication, the artistic point of view, and human consciousness itself.
Howard, Kimberly. Keep your tax records for a minimum of 3 years. After that, it depends on your situation as to the length of time. If you wrote off a bad debt, better keep them for 7 years. If you have a small business, 7 years may serve you best. Be sure to keep not only a copy of the return, but all the supporting documents.
It depends on how accurate your return was, what records you are talking about, etc. It's anywhere from 3 years, to 6 years, to forever. 6 years might be a good idea, especially for collection reasons. In many cases, the IRS will require the last 6 years of returns before working with taxpayers. If the IRS lost your return, you might need to resubmit it--so maybe 6 years generally, and 10 years or longer if you think the return might be incredibly weird.
