Bad Design Kills [1] have found a treasure of logo-twins, and show them all off in the Logoworks rip-off collection [2]. By the looks of it, logoworks work is often to close for comfort when compared to other logo works.
What do you think folks, a case of plagarism conveyer-belt style, just change a dash of color here and there, et voila a fresh new logo - or a strange series of amazing coincidences?

Some of the designs seem like clear cut ® trademark ingfringing Xerox copies to be honest.
Logoworks [3] was most recently mentioned around here for trying to get their spinster co-worker a date [4], as a 31 year old unmarried lad is fast approaching his sell-by date in Utah. Who knew.
