This book has for years been the only book. It has an acurate biography of LS Lowry and a good selection of colour plates and B/W pictures of state owned Lowry's works. It is an essential resource for any one wanting to research Lowry
However.. there are recent books that let you deeper into his personality and others that have better pictures.
For kids get Lowry lexcorn or LS Lowry by David Maclean
If you want a good biography get Shelley Rhodes.It is a better read.
I have all the books but this is my reference book
I would not be without it.
