DeLisle Stewart discovered IC 2220 = DS 315 on a plate taken in 1908 at Harvard's Arequipa Station. He noted "!! Nebula involving [HD 65750], extends 2' in dec and 1' in RA, 2 B and 2 F spiral wisps, spiral in form."

IC 2220 was named the Toby Jug Nebula by Paul Murdin, David Allen and David Malin in their book "Catalogue of the Universe" published in 1979. David Malin included the Toby Jug Nebula in his 1999 book "The Invisible Universe" and wrote, "A few degrees from the bright star Avoir and a little south of Miaplacidus is a curious nebula with the uninspiring catalog name IC 2220. It has a popular name taken from its superficial resemblance to the profile of a toby jug, a traditional English beer mug with a large handle, with one side molded as a stout character with a rustic, painted face. My colleagues and I suggested the name Toby Jug in our book "Catalogue of the Universe" in 1978, and it seems to have stuck, even in the United States, where toby jugs are rarely seen."

300/350mm - 13.1" (1/30/06 - Costa Rica): at 105x the "Toby Jug Nebula" is visible surrounding a bright red variable star, V341 Carinae and was easy to chase down just 1.6° north of the naked-eye open cluster NGC 2516. The nebula appears as a large, irregular glow unfiltered. With careful viewing the west side is bowed in with thin extensions to the west on the north and south ends. The nebulosity is not as extensive on the following side of the star.

13.1" (2/17/04 - Costa Rica): The "Toby Jug Nebula" is an unusual bipolar red reflection nebula 1.5 degrees north of NGC 2516. Unfiltered at 105x, a fairly large irregular glow is visible surrounding the bright red M-class variable V341 Car = HD 65750 (mag 6.2-7.1). The nebula is bowed towards the west with the curved section on the following side of V341. It extends furthest to the NW and the SW and is indented and weaker due west of the star. The total size of the "Toby Jug" is 2'-3'.
