1905 - 1910 Clown Band RPPC - Washington Park - Brooklyn??
 

I've had this real photo postcard for quite a few years and have been trying to figure out which ballpark is shown in the image. The postcard is dated between 1905 and 1910, based on the AZO stamp block with four diamonds on the back. A sign held by a band member in the photo reads, in part: "Baseball Today, County City," "Washington Park," and "Come See the Fun." Any insights or thoughts would be greatly appreciated. Thank you!

There were several incarnations of ballparks named Washington Park in Brooklyn. There was also a Washington Park in Indianapolis (and one in LA but it was opened in 1911).

I tried interpreting the sign to mean "County: Washington" and "City: Park" but could not find a Park City that was in a Washington county.

Near 100% sure it's not Brooklyn; it was a city and then became a borough, and sure technically it's the county of Kings but I don't think anyone would use "county" on a sign to promote something.

Looks like there's some very faint writing above that? Is there enough to try to rescan and play with adjustments? Looks like it ends in "...men"
