Old ledgers, clocks, typewriters and photo albums are just some of the items in the extensive PwC archive. To mark our 175th anniversary, we're selecting some of our favourite artefacts embodying our identity and purpose, and delving into their history. We have picked items which, in their own way, get to the essence of who we are and what we do, and illustrate why our people will always be at the heart of the 175-year PwC story. Look out for more to come in the months ahead.
