This is what happens when a hungry worm visits your collection ... (not mine)

Bicycle, Bicycle, I want to ride my old Penny-farthing Bicycle

Penny-farthing Bicycle 

Penny-farthing, high wheel, high wheeler, Man slicer and ordinary are all terms used to describe a type of bicycle with a large front wheel and a much smaller rear wheel that was popular after the boneshaker, until the development of the safety bicycle, in the 1880s.[1] They were the first machines to be called "bicycles".

Some Swedish versions of the above (but not Penny-farthing)
