This Eastman postcard I purchased awhile back on Ebay, the price in my range of $5.79. There were several items after reviewing allowed me to figure out when it was taken. The Christian Science Church on the corner of Mill and South Lassen Streets was constructed in 1938. Also built that year, was the Purity Grocery Store on South Lassen Street across from the Methodist Church. Both buildings, by the way, still exist, just under different ownership.
On South Roop Street, where the current Lassen Municipal Utility District building is located, appears as a vacant lot. Work on the construction of that building started in the fall of 1939. It should be noted that building was originally constructed for Safeway.
