I will have to ask my aunt Alice whose writing this is on the card.
I think it is the handwriting of the woman who eventually received the catalog - Mrs. Thomas Leonard, 96 Neptune Avenue, Deal, New Jersey.
Apparently the catalog was sent out to one person but was returned to the sender (the Block Shop). Ms. Leonard must have requested a catalog but they had run out. So they sent her a "returned" BLOCK SHOP catalog with their regrets.
And I own the cataglog now.
