I think the Lovelites put pictures of themselves on this release because there was another girl band with the exact same name who were touring and and getting bookings on the Chicago groups sucess. The pic were an effort to put a stop to this, I guess, by showing what the real girls looked like. This has me wondering if the issue without the pic is in fact the earlier one.
If you dont have it, pretty much every track on their Uni LP is good.
