If you want to see Hairy Styles with Three Testicles, head to the Linnean Society in central London, where a curious new exhibition has just opened. In this case, Hairy Styles isn’t a pop star, but a playful collection of hairy specimens and the three testicles appear in a notebook on display.

Display case in a library featuring various historic drawings of horses and a carved wooden piece, with informational text visible on the side.

Inspired by the grand tradition of the cabinet of curiosity, or Wunderkammer, which flourished in 17th- and 18th-century Europe, the exhibition brings together a series of themed displays showcasing some of the Linnean Society’s more unusual treasures.

A display case featuring various botanical specimens, including dried plants, an illustrated book, a photograph, and labeled boxes with natural history items.

It’s a gently whimsical show that’s more “look at this oddity” than “here’s a scientific explanation” and that’s a large part of its charm. Expect moments of delight, fascination, and the occasional shudder of “ugh!” as you peer at the exhibits.

Among the curiosities are animal skins, a pipe (reportedly) carved from an albatross bone, and preserved spiders, all contributing to display a suitably spooky air for the Halloween season.

One particularly eye-catching item is a handwritten dinner bill from the King’s Arms in Kew, dating back to Carl Linnaeus’s visit to London and a far cry from today’s plain thermal till receipts.

A historical document displayed in a glass case, featuring a decorative crest at the top and handwritten names and details below. Other papers are visible around it, showcasing various handwritten notes.

And keep an eye out for the hexagonal postage stamps; you don’t see many of those about.

As for the famous testicles, they take a bit of finding. A helpful tip: use your phone camera to zoom in on the notebook page to read it.

Handwritten page of text, with some words highlighted, and a small illustration or emblem in the top left corner. The text appears to discuss a monument or location and is filled with cursive handwriting.

That the curators have had a bit of fun with the labels is also a nice touch – science should be engaging and fun at times.

The exhibition, Wonder, is at the Linnean Society on Piccadilly until March 2026.

It’s open Tuesday to Friday from 10am to 5pm and is free to visit.

A glass display case in a library showcases various books and artifacts, surrounded by tall shelves filled with books. The interior is well-lit, creating a contrast with the dark wooden shelves.
