Scully on the deviant art site has shared a huge number of Photoshop brushes. Some based on henna designs, others on old letters and yet others based on damaged film. Browse scully7491’s Gallery to see them all. I particularly liked the brush based on scanned images of ancient maps and another set based on close ups details of bark on trees.
Amoung the brushes on offer at the 500ml site there are brushes with a 1930’s fashion theme, vintage cameras, and an Art Nouveau theme.
Thank you for great links. It’s always a treat to find new photoshop stuff to play with :))
