I was looking through the dollar boxes at a local show, and found a few Australia Covers. These two, though, has this stamped prominently on the back (Walter G Crosby, Stamp Collection. Philatelist Since 1928 d. 1947):

Now I know that Walter Crosby was involved in the design of various Cachets found elsewhere on this forum, and he died in 1947, but these covers have no cachet. Could they have been part of his collection and sold to people after his death?


Note that both of them were sent to Mrs. W J Evans in the Los Angeles area.
