PaulLeon, your card is an E121, but labelled E122.
For the benefit of bballdude, E121 cards look like the one Leon posted. E122s are similar, but the name at the bottom appears in a grey box. E126s were issued several years later (1927) and have a very shiny surface. The E126s also have a card number (between 1 and 60) on the front.
