American Canadian Air Lines Inc stock certificate 1930's (Boston MA)

Rare airline collectible.  Very nice vignette of the company 1920's aircraft (artist rendition) A-CAL lettering. Unissued and not cancelled. Dated 19__. Circa 1930 from company bankruptcy.

Incorporated in Boston MA around 1930, the company ran passenger routes from the US Northeast and large Canadian cities but was dissolved in 1932 due to the Depression impacting business and lack of mail business that flaoted the larger companies of the time. Little else is known about the company.
