Thank you for submitting your item for appraisal. This appears to be a recent giclee print after a comic cover from 1982, depicting the The incredible Hulk TV-sensaton etc. The print in your possession is one of the 19 artist proofs. No identical prints were sold in the recent past. Similar prints were sold at auction. The estimate is based on these results. There is no measurement for the sentimental value you might attach to the item. A true Stan Lee or Hulk enthusiast might be willing to pay more than the high estimate.
