Illustrated sports-themed trading cards consistent with Upper Deck Looney Tunes series

A pair of printed trading cards featuring a crossover of Major League Baseball and Looney Tunes animation, appearing to be from the early 1990s. The top card shows an illustration titled 'Baseball Appreciation' with characters Granny and Tweety Bird watching a pitcher on a television screen, while the bottom card displays a trivia question regarding the numbers '9, 11, 12, 14, 15, 16, 17' related to 'Nolan.' The cards bear logos consistent with 'Upper Deck,' 'Major League Baseball,' and 'Warner Bros. Inc.' The bottom card includes the number '152' and an 'ACME' logo mark. The cards are housed in clear plastic protective cases. Given these logos are printed directly on the material, they are consistent with a commercial production from 1991 or 1992, though physical inspection would be required to rule out later reproductions. The cards appear in good visual condition with no obvious creasing visible through the holders.

I have reviewed the images of the two trading cards featuring a crossover between Major League Baseball and Looney Tunes characters. Based on my visual assessment, the cards appear consistent with the 1991-1992 Upper Deck Looney Tunes Comic Ball series. One card depicts 'Baseball Appreciation' with Granny and Tweety Bird, while the other serves as a trivia-oriented card (No. 152) referencing pitcher Nolan Ryan. While the printed logos for Upper Deck, MLB, and Warner Bros. suggest they are part of this specific commercial production, I cannot verify the physical integrity or paper stock from a photograph. Physical inspection would be required to rule out later reprints or high-quality reproductions. The value of $5.00 to $15.00 is based on the assumption that these are standard production cards in good condition. Items of this type are generally mass-produced, and their market value is driven primarily by nostalgia and the intersection of animation and sports collecting. The clear plastic cases suggest they have been protected, though I cannot determine if there is minor surface wear or edge chipping under the holders. General market behavior for these specific series shows high availability, which keeps prices modest unless the cards are professionally graded in gem-mint condition. Should these cards be identified as later reproductions or unofficial 'in the style of' prints, their value would be negligible, likely under $1.00. To confirm the assumed identification, an in-person examination of the holographic security features typically found on Upper Deck products of this era and a microscopic analysis of the printing dot patterns would be necessary.
