The primary tie to Mercury in ability is the fact that his weapon are his boots/greaves. He can probably use the firing mechanism to make move faster or jump higher, but we haven't seen him use them this way.

Mary Poppins was first published a mere 40 years after L Frank Baum's Wizard of Oz which was just about 35 years after Alice in Wonderland. Classic, in this case, more or less implies anything prior to the 1960s and perhaps 1950s. It also seems to want to be anything that didn't start as a movie, cartoon, etc. It had to start as either a book or a tale passed by word of mouth (i.e. the original tales that inspired the Grimm tales)
