Very nice pair of rare vases in the brutalist style by shelf pottery
.Shelf Pottery was a studio pottery business founded near Halifax in the 1970s, initially by an art teacher as a hobby in he’s garage. 
The company eventually went into liquidation in 1998,  and now hes pottery is very sought after by collectors.
Very unusual to find shelf pottery in this size let alone a pair!
