I used to bank at the Mariners Savings and Loan in Newport Beach in the late 70's. They had these very cool drawings done by Mark Leyson that they gave to their customers. One day Mark Leysen was there to sign his drawings. Below are four of the set of 8 drawings that were signed by him and are all numbered 8/100. Part 2 with four more drawings tomorrow.
Here is a link to the Legacy Arts Studio and Gallery website with more information about Mark Leysen.
