Michael Bruno, founder of online art and antiques retailer 1stdibs, and his partner Alexander Jakowec, recently hosted a Maison Gerard exhibit of 20th-century sculptor and architect Marino di Teana on the landscaped gardens of their Southampton home, a Grosvenor Atterbury-designed mansion on Coopers Neck Lane.

Maison Gerard, the famed Manhattan gallery and store, is running the exhibit, on view until Aug. 26, which can be seen by appointment only (212-674-7611).

Our spies say Bruno and Jakowec’s Hamptons spread — purchased for around $15 million in 2015 — may soon be going back on the market.

The couple is spending more time at their new home in Maine, which they bought last fall for about $4 million.

It’s on Deacon Browns Point in North Haven.
