This was a new one on me, I'd never heard of this before. This is a trading card from Sugar Daddy candy. While I have seen (and even remember getting) trading cards out of Sugar Daddy candies, I never knew there was a Disney series, nor an Alice in that series.
This Alice is card number 20 out of a set of 25 cards called Mickey Mouse and his Pals, series number 5. Don't know if this means 5th series of Mickey and pals, or 5th series overall.
I also don't have an exact date on this, but the art tells me that it is most likely from the 1960s. If anyone has details on this series or knows if there were other Alice characters from that series, I'd be grateful for that information.
