You can buy prints of the photographs on Streets of Liverpool from the Fotolore online store. Fotolore is another project of mine which launched in September 2012, featuring 100s (and eventually 100os) of old images of Liverpool.
The store is powered by SmugMug, a leading photo printing and sharing site. After trialling various photo printing providers, we chose SmugMug as their print quality, website and customer services was easily the best.
The prints come in a variety of sizes and finishes. Prices start from £5.99
As well a prints I can also license some of my photos of liverpool for commerical use. See the Licensing page for more details.
