Posting Box, St Aldate's

Doesn't everyone have a bit of a thing for post boxes? After all, how many wooden ones have you seen? Aren't you just a little intrigued that the plates which state 'First Class' and 'Second Class' actually cover the original division of mail into different boxes for 'Local' and 'National' mail? Doesn't it excite you that the letter box has a large hole beneath it which originally took letters straight down to the basement? Or is it just me?
