The Greater Manchester Centre for Voluntary Organisation has rebranded to create what it says is a more modern identity.
The organisation, which represents voluntary groups in the city, has adopted a new logo and strapline: "Supporting voluntary action in Greater Manchester since 1975".
Stationery, signs, advertising materials, publications and the charity's website have also been redesigned.
The organisation said its branding was no longer suitable and appointed a design team to create a "more appropriate, modern identity that better reflected the values of GMCVO".
Andrew Ward, marketing officer at GMCVO, declined to say how much the rebrand had cost. He said the sum was "fairly substantial", but "not a ridiculous amount".
"What we had before had been around for a long time and it didn't reflect the many facets of the organisation," said Ward. "It seemed a bit old or staid."
The Manchester-based design studio Transmission Creative carried out the work.
