Twinkie panel cards match "normal" Hostess in picture and design, other than black bars just above and below the back's career stats box. While yellow cake stains are a strong hint, collectors usually look for the bars to positively identify a "Twinkie card."
Note that this set's specifically made up of single-card panels and uses the "Twinkie" designation for convenience. Larger snack cake packages, including Twinkies, offered three-card panels on the box itself, but card catalogs call those part of the "normal" Hostess issue. (Again, it comes down to the black bars shown above.)

Value: Trimmed singles cost a dollar or two and complete panels cost a bit more due to rarity.
