You know that urge to reward yourself when you are frustrated, perhaps getting yourself a cone of creamy, tasty ice on a hot summer's day? I felt the same when I noticed how much Google's Search by Images frustrated me. So I came up with a rewarding puzzle where this malicious tool won't help you much, because it can't associate, even if it tells you where the picture in question comes from.
In the following you will see ten ice cream vans and ten other vehicles. All you have to do is to find the correct pairings and the connection beneath. These connections may be various, some may be a bit more straightforward, some will take more effort. In German, we say you have to "think around the corner". You don't have to identify the vehicles necessarily, as I don't know all of them myself. Sometimes I have modified the pictures to make them harder to identify, sometimes to make the connection less obvious.
One point for each right pairing together with the right reason. Have fun!
