I prefer NOT to have my name, family name or business name attached to donations via signs, dedication pamphlets, etc.
That said, I am often asked to permit it, because the organization needs to show ‘prominent names’ in order to successfully solicit other donations. In our local hospital the CTL Law Firm Name is on an exam room in the ER. This was used to solicit other similar donations from area law firms. Our competitors did not want to look bad in the eyes of the general public (potential clients). Now, every single exam room has been dedicated/paid for by a local law firm. That is not a bad thing.
There are tax caps on charitable giving (in the USA), so many businesses insist on the signs for major gifts and instead of take charitable donation deductions, expense this money as advertising.
None of my personal donations have signage saying donated by CTL, but there are signs (for example) saying donated in the memory of ‘CTL’s Father’ without identifying the donor.
