Monochrome Madness #65 – Numbers Literally

The theme for this week’s edition of “Monochrome Madness” comes from Sarah (Travel with Me).
We’re supposed to find monochrome images featuring numbers.
As a non-native speaker, I can’t imagine what “literal numbers” are. Numbers are just numbers, and when you put them in any context, are they then “literal” or “not literal”? So my photos simply show numbers somewhere, without me knowing whether they’re literal or not.
