Yes... and... I don't see a question

I have a 1923 binney & smith company uncle wiggily water color tray (all metal) with what I think should be signed as lansing or lang campbell for the signature as the artist... I can clearly see (with a magnyfying glass) the name iang campbell, an 'i' instead of the 'l' for 'lang'... is this a mistake and if it is, is it worth anything? I hope this question made it... thanks tickle...
