From The LeBlond Book by C.T. Courtney Lewis, page 94:

On the right we see the business premises of ‘Mr. J. Armstrong, Smith and Farrier,’ at whose door is a man holding two horses, which no doubt require shoeing, if they can receive attention this day. Next to Mr. Armstrong’s is the ‘Swan Inn,’ in front of which is a Jack-in-the-green, with attendant music and mummers. Villagers are looking on, and even the little dog in the center seems laughing to see such sport. Strutt, in his ‘Sports and Pastimes,’ 1831, says: ‘The chimney-sweepers of London have also singled out the 1st of May for their festival; at which time they parage the streets in companies, disguised in various manners. Their dresses are usually decorated with gilt paper, and other mock fineries; they have their shovels and brushes in their hands, which they rattle one upon the other; and to this rough music they jump about in imitation of dancing. Some of the larger companies have a fiddler with them, and a Jack-in-the-green, as well as a Lord and Lady of the May, who follow the minstrel with great stateliness, and dance as occasion requires. The Jack-in-the-green is a piece of pageantry consisting of a hollow frame of wood or wicker-work, made in the form of a sugar-loaf, but open at the bottom, and sufficiently large and high to receive a man. The frame is covered with green leaves, and bunches of flowers interwoven with each other, so that the man within may be completely concealed, who dances with his companions, and the populace are mightily pleased with the oddity of the moving pyramid.’ These scenes, common some sixty years ago, have now disappeared from our streets. It makes a good contrast to No. 102. The print is signed on the bottom centre.

There are some skillfully executed, quite modern, reprints of this. Look carefully at the mounts, as the quality of the material of which they are made indicates the spurious origin of the print on them.
