Atrium Gallery

Atrium is a ‘selling’ prints gallery rather than a ‘come and see our posh paintings’ gallery — and they sell lovely prints and posters.
Within the Podium shopping centre (with Waitrose), it’s a double-​fronted shop with many, many prints at reasonable prices (not cheap) which you can buy framed or unframed. Last time I bought was unframed and they gave me a poster tube as it was being posted overseas (at the Post Office just across the road!).
Good service, I’ll definitely buy again.
