This font taken from an old magazine - is it a recognised font or a one off artwork? K

definitely hand-lettered...

To duplicate the lettering using a font would take a lot of editing in illustrator or whatever program you might prefer for designing with vectors. If you do tackle the project there are a variety of candidates in the heavy "bulbous serif" category that you could use as a starting point. In no particular order:

Thanks very much for the help. I found a similar type used on the Rolling Stone magazine logo, but its not so bulbous - a bit 'sharper' - Royal Acid Bath - but as you advise, it will be necessary to originate it from scratch based on another font.

Thanks again Kieron
