I came across a digital version of Kommos 4, edited by J. and M. Shaw, on the University of Toronto's institutional archive [worldcat]. The text is here. The plates here. Oddly, the plates are distributed under a Creative Commons "Attribution - Non-Commericial - No Derivatives" license, whereas the text has the more generic statement, "All items in T-Space are protected by copyright, with all rights reserved."
For myself, I'm glad to have Hayes' discussion of the Roman pottery on my hard drive. It begins on p. 310. The relevant plates begin on the twelfth page of the PDF file titled "Kommos_volume_4-2_256-275". You'll see what I mean if you follow the links given above.
But there's much of interest in this publication, something for most everyone really, so I recommend downloading all the files.
