I got "UR, the first phases", first edition in a book sale. When I got home and looked a little closer I noticed it appears to be signed. It cost me £5

I'm pretty sure its real, Woolley is a bit too obscure to bother faking, photo attached. His scrawl is almost illegible

The ink seems to have soaked through to the reverse of the page and I know that's a factor of 1950s fountain pens on cheap paper (book was mass produced)

Anyone have a opinion ?

Thanks to all
