Excellent new sheet music site. Just Googling 'Musical Bouquet' should take you there.

Musical Bouquet run by Chas. Sheard published sheet music from c1850 till into the 20th century. The website gives a full list of their output plus dates and serial numbers and where available thumbnails of the covers.

Just added to the site is a shop with tons and tons of sheet music from the 18thc to the 20thc. Prices are about average compared with other sites and they take PayPal.

There's some Harry Clifton, Arthur Lloyd, Vance material, but I've just snapped up 2 of the Cliftons. Some interesting trad music including Child ballads on the Scottish page.
