I have recreated some (vector format) logos etc. from (pixel) images for fan art purposes.
For vector drawings, I use the free software Inkscape. In case you are interested in suich drawings, I can really recommend this software. There are plenty tutorials on the interweb.
The MOS Technology logo was recreated from a logo on an original data sheet.
There are two kinds of vector graphic files: white and black. The font of the text line is "Arial Rounded MT Bold". It was used to approximate the original font. Is was converted into pathes, so downloading the font is not required.
There are the scans of Cris Yaneff's draft of the Commodore logo. The following SVG files were recreated from them.
There is a grey and a colored version.
