This image shows an early photo of the Santa Fe and Disneyland railroad train and station, with the original floral Mickey Mouse illustration.
The description states:
The DISNEYLAND entrance, set in flowers, is as beautiful as DISNEYLAND itself is wonderful. The Santa Fe and DISNEYLAND railroad station sits atop the berm in all the glory of a transportation center of the 1900s.
–Over time, the Santa Fe name would be removed and the name shortened to the Disneyland Railroad. This image dates from shortly after the park opened in 1955.
